SIM tool inserted into lower mic of S9+

I bought an unlocked Galaxy S9+ on Amazon and went to AT&T to get a new nano SIM card (my previous Note had a micro). The idiot AT&T employee went to eject the SIM slot and poked the tool into the lower (main) mic hole….could she have damaged the mic?

I did some voice recording tests and it doesn’t appear to be damaged but unfortunately because it wasn’t me, I don’t know if she wiggled it or it went in too deep. I’ve seen that the top mic is offset to prevent these types of issues but haven’t heard anything about the bottom mic.

Is there anything else I can do to test?

Thank you!
