Might I have damaged the top mic(?) by poking it like a SIM card tray?

I foolishly mistook the hole on top of my new Pixel 3a XL (I think it's a mic?) for the hole to open the SIM card tray, not being careful to check for the actual outline, and poked it once moderately hard. Might I have damaged it by doing so? I've read some phones are designed to prevent damage in this way, but I'm not sure about mine. I'm also not sure how to test it for performance that's deficient compared to what I should expect (i.e., deficiency instead of full failure); any advice for that?
