Is my iPhone 12 toasted? Or still repairable?

Hey, I am on vacation and my iPhone 12 max pro slipped Into the pool. It was in 2 feet deep water and 5 minutes max. I thought the 12 max pro was supposed to be water resistant for up to 30mins but somehow this caused condensation to build up in the 2 left cameras and front camera. initially this causes Face ID to turn off and it later experienced problems with the sim. I’m using e-sim outside of the US, so for some reason this wasn’t connecting to the local network provider. Then these problems seem to fixed itself but lock button starting experiencing problems. It kept locking itself and holding on until it dialed sos. (Took me many tries to finally beat it the setting menu and disable auto-sos dialing).

It’s day 2. Phone was working except still problem with lock button. I tried turning phone off but because lock button issue, it kept turning back on (no, the lock button is not depressed or stuck). I found some desiccate package from local snacks and I tried wrapping the phone in a small bag with the desiccate package.

Day 3: battery finally died. When charged - Lock button won’t work (so I can’t turn on) and my phone is now showing “plug into laptop to restore” symbol. I was seeing this on day 2, but sometimes it would load up to Home Screen where I can unlock and use phone for a little bit. Now I don’t even see that and I’m worried.
