Hide or show a custom menu bar icon

I have made two triggers that respectively enable and disable an audio equaliser app. I would like to know whether the EQ is on or off at a given moment.

So I would like to use BTT show a custom menu bar icon when I run the "enable" trigger" and remove the icon (or change it's icon to something else) when I run the "disable" trigger.

Any ideas how I can achieve this?

Here is an example that shows on/off:

Menu Bar - Button on Click - Discussion & Questions - BetterTouchTool Community (folivora.ai)

You could modify this script to also call some action or named trigger to turn eq on / off. How does your current setup for this look like?
