It's urgent!!!

Pejo 308 cc. The other day, I made the mistake of washing the car with pressurized water at close range. I don't know what happened, but when I want to open it, I lower the windows and it works from the rear trunk, but it doesn't open.

like it's stuck somewhere. Anyway, I opened it so I could fix it, maybe I accidentally took out the piece below :)

now what is the name of this piece and where can I find it?

thanks.
