microphone icon always appears whenever I use google meet

hello, I'm having trouble with my MacBook Pro here. In this quarantine time, I use video conference tool like zoom and google meet a lot. but the thing is, whenever I use google meet (using safari), a microphone icon suddenly popped up on my menu bar and I can't do anything about it. it won't go away from the menu bar UNLESS I turn my MacBook off, even when I already close the tab and the safari window. its been budging me because I'm working on my paper and I have so many files opened and safari windows that really can't be closed because it is very important it will mess up my work. I already searched everywhere for this problem's solution without having to turn my MacBook off but failed to do so. Anyone, please kindly help me. thank you 🙏 ps it won't budge even when I click the "unmute for google meet" the icon is still there, and still like that.
