Struggling to Completely Remove Webex Extension from Safari — Any Permanent

Hey everyone i am hoping someone here has dealt with this issue before.

I’m using macOS 26.1 and I’m trying to remove the Webex extension from Safari. I ahve already uninstalled the Webex app, manually deleted visible Webex and Cisco files, and even removed the extension from Safari settings but it keeps coming back whenever I try to make a call in Safari.

I also contacted Apple Support and was redirected to Webex Support, but still no luck so far.

Has anyone found a permanent solution to remove Webex completely from Safari?
Is there a hidden component, system extension, or launch agent that needs to be removed manually?

Any guidance steps or scripts that worked for you would be highly appreciated.
Thanks in advance!
