Apple Watch’s display stopped working after getting slightly wet

My apple watch series 8’a display stopped working after getting slightly wet in a jacuzzi. The apple logo showed up and nothing else since then. However, it’s getting connected to my iPhone and getting charged and vibrating for notifications as well. I’m even able to track my workouts and sleep with it so I kept wearing it. Today, the watch got an update and i clicked on install hoping it would fix itself. But a prompt saying “Recover apple watch” shows up on my iPhone and after clicking on continue, it’s asking me to enter a 6 digit displayed on my watch. But ofcourse I don’t see anything as the display isn’t working. Now the watch isn’t showing as connected on my iPhone. What do I do???
