Micro SD Card data recovery - Fell in salt water

Hello,

So my sandisk micro sd card fell in salt water. Or my drone did and im trying to recover the files. I get the message "not recognized" I clean it, dried it out and still nothing.

I did the disk utility first aid. I created a new partition and i see the gigs or data are still in there, i just can't get to them. Im stuck at that step. any help? thanks!
