UEFN Linked My Project to the Wrong Island — How Do I Fix It?!

Hi, I need help reconnecting my UEFN project to my original published island.**

I accidentally created a new project instead of updating my existing one. Now when I upload, it publishes to the new project instead of my original one (which already has a map code, thumbnail, and plays). I still have the Verse path and original project ID — how do I link my local UEFN files back to that original project?

Thanks!
