Why does my mic glitch out every time I join the call on the chats app

Every time I join the call on the chat app my friends hear a sound, that sounds like my mic is glitching out. Although my mic works just fine as it works in games and i've went to mic testing websites hi factory reset my headset. I've powered down my headset, and I don't know how to fix it. I'm pretty sure it's just a problem with the chat app. Could someone help me?
