Describe what the problem was / what the new feature is
We used the bottom sheet on Android and iOS, but on iOS the native action sheet should be used.
Describe your solution
Created a new adaptive widget using the bottom sheet on Android and the action sheet on iOS.
Applied the new widget (Onboarding, profile, add attachment)
Additional context
Small renaming
On Android everything should just look the same and behave the same
On iOS the UI for modal bottom popups should be more native now
