Is it possbile to add custom script execution for on-click event in "wlr/taskbar"?

[dirDahsul]

Hello,

I would like to do my own custom functionality for event execution.
I'm refering to the "on-click" event for "wlr/taskbar". https://github.com/Alexays/Waybar/wiki/Module:-Taskbar

Basically, would like to not be restricted to pre-defined actions:
activate Bring the application into foreground.
minimize Toggle application's minimized state.
minimize-raise Bring the application into foreground or toggle its minimized state.
maximize Toggle application's maximized state.
fullscreen Toggle application's fullscreen state.
close Close the application.

Is there a way to execute a custom script for "on-click", and if not, is there a workaround for achieving that result?
For me, I would like:
"on-click": "bash script.sh {state}", where I'm passing Format replacements to the script, even if nothing is passed to the script, I'm also okay. Is there a way to have it execute custom functionality and not be restricted?
