Can My Water-Damaged Samsung S23 Ultra Be Saved or Should I Sell It for Parts?

I accidentally dropped my Samsung Galaxy S23 Ultra in water for about 30 seconds. After retrieving it, I got a notification that the SIM card was removed on its own. I turned the phone off and placed it with the charging port facing down for about 10 minutes. Upon turning it back on, I received a warning to disconnect from charge, but it wasn't charging. The phone started beeping loudly and would turn itself on and off in a weird loop. I followed some advice and removed the S Pen and SIM tray, finding water in the SIM area, which I dried. I left the phone on a towel, but it kept beeping and displaying strange colors. After a while, the camera fogged up, and while it briefly turned on, it was unresponsive and wouldn't charge. I took it to a repair shop, but they said it was completely flooded and the repair costs would exceed the phone's value. They offered me a measly amount for parts, which I declined. I'm now wondering if there's any chance to save it since it showed signs of life initially and how much I might be able to get if I sell it for parts. Any insights?
