For a chat window, only show "X" btn via Ctrl/Cmd press

Feature Request:
Only show the “X” btn for a chat window, when pressing Ctrl/Cmd

Reason:
This will prevent accidental closing of a chat window.
When switching between chat windows, it is easy to press the “X” btn. Specially on laptops. Also, the chat window closes without any warning.

Severity:
Low

Thank you for considering whenever feasible :victory_hand:
