What's new in this PR?

Issues

After recent changes the button Show all Participants was not sticky to the bottom anymore.

Causes (Optional)

There was a change from Scaffold to CollapsingTopBarScaffold which has a specific parameter for bottomBar.

Solutions

The solution was to revert back to Scaffold due to not trying to have extra logic to handle the bottom button visibility in CollapsingTopBarScaffold (handling changes on tab rows).

Testing

How to Test

• Open App
• Open Conversation
• Open Conversation Details
• Click on Participants (must have be a group with 5 or more participants in order for the button to show)
• Show all Participants button should be sticky to the bottom as before.
