How to toggle microphone off/on?

On macos (Monterey/version 12) how can I toggle the microphone off/on (mute/unmute)? If there's no control for this, is there a way to script it for macos specifically to achieve the desired effect of quickly toggling the microphone? Various apps use the microphone (eg web/webrtc calling, desktop calling/meeting apps, etc) and don't actually mute when I select that option, they simply turn off the audio stream. How can I control my own microphone from the OS instead of the various oddities and quirks of app developers (regardless of whether it's in browser or otherwise)? Thanks.
