PR Author Checklist

• [x] I linked the correct issue in the ### Fixed Issues section above
• [x] I wrote clear testing steps that cover the changes made in this PR
  • [x] I added steps for local testing in the Tests section
  • [x] I added steps for Staging and/or Production testing in the QA steps section
  • [x] I added steps to cover failure scenarios (i.e. verify an input displays the correct error message if the entered data is not correct)
  • [x] I turned off my network connection and tested it while offline to ensure it matches the expected behavior (i.e. verify the default avatar icon is displayed if app is offline)
• [x] I included screenshots or videos for tests on all platforms
• [x] I ran the tests on all platforms & verified they passed on:
  • [x] iOS / native
  • [x] Android / native
  • [x] iOS / Safari
  • [x] Android / Chrome
  • [x] MacOS / Chrome
  • [x] MacOS / Desktop
• [x] I verified there are no console errors (if there's a console error not related to the PR, report it or open an issue for it to be fixed)
• [x] I followed proper code patterns (see Reviewing the code)
  • [x] I verified that any callback methods that were added or modified are named for what the method does and never what callback they handle (i.e. toggleReport and not onIconClick)
  • [x] I verified that comments were added to code that is not self explanatory
  • [x] I verified that any new or modified comments were clear, correct English, and explained "why" the code was doing something instead of only explaining "what" the code was doing.
  • [x] I verified any copy / text shown in the product was added in all src/languages/* files
  • [x] I verified any copy / text that was added to the app is correct English and approved by marketing by adding the Waiting for Copy label for a copy review on the original GH to get the correct copy.
  • [x] I verified proper file naming conventions were followed for any new files or renamed files. All non-platform specific files are named after what they export and are not named "index.js". All platform-specific files are named for the platform the code supports as outlined in the README.
  • [x] I verified the JSDocs style guidelines (in STYLE.md) were followed
• [x] If a new code pattern is added I verified it was agreed to be used by multiple Expensify engineers
• [x] I followed the guidelines as stated in the Review Guidelines
• [x] I tested other components that can be impacted by my changes (i.e. if the PR modifies a shared library or component like Avatar, I verified the components using Avatar are working as expected)
• [x] I verified all code is DRY (the PR doesn't include any logic written more than once, with the exception of tests)
• [x] I verified any variables that can be defined as constants (ie. in CONST.js or at the top of the file that uses the constant) are defined as such
• [x] If a new component is created I verified that:
  • [x] A similar component doesn't exist in the codebase
  • [x] All props are defined accurately and each prop has a /** comment above it */
  • [x] The file is named correctly
  • [x] The component has a clear name that is non-ambiguous and the purpose of the component can be inferred from the name alone
  • [x] The only data being stored in the state is data necessary for rendering and nothing else
  • [x] For Class Components, any internal methods passed to components event handlers are bound to this properly so there are no scoping issues (i.e. for onClick={this.submit} the method this.submit should be bound to this in the constructor)
  • [x] Any internal methods bound to this are necessary to be bound (i.e. avoid this.submit = this.submit.bind(this); if this.submit is never passed to a component event handler like onClick)
  • [x] All JSX used for rendering exists in the render method
  • [x] The component has the minimum amount of code necessary for its purpose, and it is broken down into smaller components in order to separate concerns and functions
• [x] If a new CSS style is added I verified that:
  • [x] A similar style doesn't already exist
  • [x] The style can't be created with an existing StyleUtils function (i.e. StyleUtils.getBackgroundAndBorderStyle(themeColors.componentBG)
• [x] If the PR modifies a generic component, I tested and verified that those changes do not break usages of that component in the rest of the App (i.e. if a shared library or component like Avatar is modified, I verified that Avatar is working as expected in all cases)
• [x] If the PR modifies a component related to any of the existing Storybook stories, I tested and verified all stories for that component are still working as expected.
• [x] I have checked off every checkbox in the PR author checklist, including those that don't apply to this PR.
