FaceTime Allow/Block message

Norton Security 8.8.7. 

MacOS 13.4.1 on MacBook Air M1.

In FaceTime call roughly every minute a notification box appears from Norton Security asking about Blocking or Allow connection. Clears on pressing 'Allow' button but then reappears around a minute later. Doesn't block the call just very intrusive and annoying. Regular FaceTime user.

I've asked this thread be moved to the Mac forum board for better exposure to Mac users.
