👋🏽
QA team, we would help us to verify that we are sending the correct telemetry for the below user's interaction? :)

When the app starts we want to send metrics for:

• Category customize_home.most_visited_sites
• Category customize_home.jump_back_in
• Category customize_home.recently_saved
• Category customize_home.recently_visited
• Category customize_home.pocket

When users go to Settings -> Customize -> Home and toggle

• "Show most visited top sites" -> Event preference_toggled with the extra keys most_visited_sites true or false
• "Jump back in" -> Event preference_toggled with the extra keys jump_back_in true or false
• "Recently bookmarked" -> Event preference_toggled with the extra keys recently_saved true or false

When clicking at the end of the home screen the "Customize home" button, we should send the event Category home_screen.customize_home_clicked, this only shows when one of these features are active Show most visited top sites, Jump back in or Recently bookmarked.

When clicking the menu item on the three dotted menu item, we should send the event "Category home_screen.customize_home_clicked.
