Things to look for during review

• [ ] Make sure all references to iot or bx class prefix is using the prefix variable
• [ ] (React) All major areas have a data-testid attribute. New test ids should have test written to ensure they are not changed or removed.
• [ ] UI should be checked in RTL mode to ensure the proper handling of layout and text.
• [ ] All strings should be translatable.
• [ ] The code should pass a11y scans (The storybook a11y knob should show no violations). New components should have a11y test written.
• [ ] Unit test should be written and should have a coverage of 90% or higher in all areas.
• [ ] All components should be passing visual regression test. For new styles or components either a visual regression test should be written for all permutations or the base image updated.
• [ ] Changes or new components should either write new or update existing documentation.
• [ ] PR should link and close out an existing issue

@Akshat55 @zvonimirfras any updates here? Trying to close out any stale PRs

[zvonimirfras]

I think we're not merging this at this point. @Akshat55 double check and close, pls 🙂

[Akshat55]

@davidicus, we aren't merging this PR now as it contains breaking changes. Will be useful in future when carbon-addons-iot-react is updated to Carbon 11 though.

Closing for now. Feel free to re-open when ready.
