How to get VoiceOver audible output when mouse / trackpad pointer hovers over screen elements

I have a Mac application.

I am in a process to make it compatible with VoiceOver functionality of macOS.


When I navigate through the screen elements of my app using keyboard, I get proper audible output using VoiceOver functionality.


I would like to know, how can I get audible output when mouse / trackpad pointer hovers over screen elements of my app.

Can anyone please assist me.
