Request to add a hotkey to mute microphone

Hello.

I would like to ask for a hotkey for muting microphone. right now I am using pavucontrol as a mixer. I used to fn+F10 (Which is the key to mute the mic on my laptop, and it corresponds to XF86AudioMicMute) on a desktop environment. I always have to open pavucontrol which is not very convenient as a hotkey.
