How to unblock camera and microphone access in google meet on safari

Hello, I accidentally blocked Google Meet microphone and camera access on Safari. Now, I cannot unblock it. I tried to do some several methods recommend on internet like go to settings >> Safari, but I cannot find Safari in my settings on Mac Book. I unblocked the access on iPhone, but it does not work on Mac Book.

Here is the suggestion from Google Meet, but I don't know where is the "Safari" menu in Pic 3.

If anyone knows, please kindly tell me. I appreciate every help. Thank you!
