Air 2S and RC PRO in salt water

The cause is for another time, but me, my Air 2S and my RC PRO fell into the ocean. I am drying the RC PRO in rice. The drone won’t start with a new battery so I expect I will have to use up one of my DJI lives. I assume from what I read that the battery should be disposed of properly. As far as the RC PRO goes, I am pretty sure DJI does not cover that. Is there any chance that it is reparable, or will I likely have to replace it?
Any advice is appreciated.
Thanks in advance.
