Microphone in chromecast devices as presence sensor

Has anyone tried using the microphone in chromecast devices as a presence sensor?

Can I create an automation rule based on polling the microphone of chromecast devices? Or similar smart speakers from other manufacturers.

And adjust the response according to the noise level

hey. did you manage too get that too work can you use the microphone as a sensor on chromecast

I haven’t found a solution to this issue yet.
I would be happy to hear about how this can be implemented.
