The entire URL of the documentation with the issue

Formatting updates:

• Replace "Fx" with "fx" wherever applicable. ( i.e. make the fx lowercase and bold )
• For each h2 (created using ##), remove 24px padding-bottom. The div that wraps up the h2 headers and the section below the header should only have a "padding-top" of 24px and no "padding-bottom".

Content updates:

• Replace the word "widget" with "component" wherever applicable. ( Please do not update the URLs )
• Events Tabel:
  • Update the event name from "onDetect" to "On detect"
  • Update the description of the "On detect" event - reference ( Please just check the sentence formatting from the given reference )
• Add a divider before the "Styles" section reference

The changes are to be implemented in two files - Next - ToolJet/docs/docs/widgets/qr-scanner.md Version 2.50.0 (LTS) - ToolJet/docs/versioned_docs/version-2.50.0-LTS/widgets/qr-scanner.md
