changing icon in apple script

Configuration Help & General Discussion
1

I found same questions, but not answers. Can anybody point me in the right direction?
I created my own mute mic button on the touchbar. When muted I want to show another icon or another color than when not muted. I understand I have to change the apple script. How? This is the script that I use

on getMicrophoneVolume()
input volume of (get volume settings)
end getMicrophoneVolume
on disableMicrophone()
set volume input volume 0
end disableMicrophone
on enableMicrophone()
set volume input volume 100
end enableMicrophone

if getMicrophoneVolume() is greater than 0 then
disableMicrophone()
else
enableMicrophone()
end if

Can you change it through alternative icon regex? Or, along the lines of how custom album art widgets retrieve the album art and set it dynamically? I don't know how to create them, but I remember seeing those two distinct methods for setting icons.

Thanks for your help, but I don't have the skills to add that to my script. I copied it from another place and have no idea where and how I should put the code

In the end I used an applescript/javascript widget with this code:

if input volume of (get volume settings) is 0 then
return "micOff"
else
return "micOn"
end if

In 'common' I can then select the icon and alternative icon + color
