Destructive actions should be suppressed when they are rare. This is the case for "Reset" or "Close Application". For a video chat, however, "Hang Up" is one of the most common actions, and one that is urgent to be able to find rapidly. As an example, Discord puts hang up nowhere near the mute/video buttons - and every time I want to leave a call I have to search for 15 seconds to find it because it's over in a corner near nothing else currently in use.
