There could be hope for it, but it might be too late now. I dumped tea on my M1 Macbook air earlier this year. I managed to save it - sort of. I had to replace the battery. The screen was working but also had liquid damage so I replaced it as well.

Immediately after spilling tea on it I shut it off, took off the bottom plate, rinsed it with water, and rinsed it again with isopropyl alcohol. I think I waved a heat gun over it for a bit and then left it in front of a fan. This was about 8 months ago and it still works!

The only lingering problem is that when caps lock is off, the light on the key is slightly illuminated. Weird, but I can tolerate that!
