Please add the ability to activate a button with the press of a physical keyboard button.

Currently some of Textra supports a physical Bluetooth keyboard, but I have found many issues when trying to activate buttons with a physical keyboard. While I can tab around to select many buttons, I cannot activate them. It would be much appreciated if spacebar or Enter/Return could activate a selected button. It seems spacebar activates some buttons, but not all, selecting a chat and sending a message being the biggest issues where a key press does not activate the button.
