Webex lets you configure meeting options to allow the host to unmute anyone.

I’ve never tried it myself as the mere concept of doing so is a huge invasion of privacy, but after learning that any meeting could have this option enabled, I no longer assume that my muted mic will stay that way.

I suspect it was implemented so the presenter could help help less technically ept people.

Get a mic with a physical button or switch to mute.

Or use Qubes OS.
