Is there a tutorial for my model, which is a SM-J337 model, because the screen has some water damage

I made a guide for the J3 2018’s screen the other night, I repaired the T-Mobile model. Here’s the link! Samsung Galaxy J3 (2018) Screen Replacement

The surprised cat not yet. You can use something like this video to get it accomplished. Hopefully you will create a guide https://www.ifixit.com/Guide/new so the rest of us can then find the repair on iFixit.
