VoiceOver screenreader fails to click button

Godot Version

4.6.3.stable

Question

I’m using the mac VoiceOver screenreader. When I navigate to a button in my Godot game, the screenreader recognizes it as such and says:

You are currently on a button. To click this button, press control-option-space.

Those keys don’t press the button. Space does, as does clicking the button with a mouse.

Is there something special I need to do to make a button clickable by VoiceOver?
