Apple Watch Series 7 - Yes I’m that person.

I literally just got the Apple Watch series 7 yesterday. I was too bloomin eager to get it up and running, I’ve pressed inside the hole on the right hand side with a SIM card key. And I pressed it quite hard as you would to get the sim holder out.

what I want to know is what is this hole for, I pressed it hard because I thought I needed to put a sim in, yes I’m stupid and I realise its an e-sim Watch blah blah, but I want to know if I’ve damaged it or reduced its water resistance efficacy. Do I need to send it in for a repair? I wanted to use it all the time including swimming etc, so I need to know what I’ve potentially damaged.

The mic is working absolutely fine, have tested multiple times etc.

the Watch is still absolutely fine, but im concerned as I don’t know what that hole is for and I felt I pressed very hard and feel I’ve damaged whatever it is. Please help. And please no ‘durrr’ comments. I’ve told myself them enough in the past 12hrs ha!
