Welcome and I have a bit of experience with water and drones:
Key is to get it into heat and let it completely dry out and DO NOT PUT POWER TO IT until you can make sure ALL WATER is dried!
Once it is dry, the next worst part is water starts to corrode just because it was once in there. So it doesn't hurt to use some Electrical component cleaner and or 91% or greater Isopropyl Alcohol to clean the circuit boards, battery leads etc.......
Then, let it dry again for days.......the entire process I wouldn't fire up something of the expense of an Anafi for around a week and would for sure find a gentle heat source to make sure it was dry before going for it.
Take care and keep us updated on what you end up with
