How to provide alternate VoiceOver text when menu bar app icon gets focus

I have a Mac application.

When this app is running, app icon in shown in top menu bar (like Wi-Fi, Bluetooth icons).


When I enable VoiceOver and bring focus on my app icon (using Fn + Control + F8), I get audible output as "application".

Instead of "application", I want to specify some different text (e.g. my app name).


Can anyone please let me know how I can achieve this.
