Selectable hardware button for sending voice messages

[sgofferj]

Many phones aimed at the outdoor community or other users which require a rugged phone have an extra hardware button for use as PTT button in Zello or as SOS button.
It would be useful if it was possible in Element to use these buttons, e.g. as "send voice message" button - a hardware equivalent to the microphone button on screen.
Especially for this use case it would be useful because the microphone screen button is at the bottom right of the screen which is almost impossible to trigger one handed for a right handed person with large hands.
