How to Delete and Rename a island from UEFN for Fortnite

How do I delete a island or rename one I know you can go to the folder that is on your PC and delete it from there but in the UEFN for Fortnite app it is still there just has a download symbol to download it so that you can re use it but not download and also how to rename a project that has already been created

@GalacticBat Thank you for your feedback. While I cannot guarantee a response, I can confirm that this has been forwarded to the appropriate team.

I also have the same problem and I can’t find anywhere how to unpublish the island. there is a button to publish it, but to unpublish it, isn’t there? A seemingly simple problem that does not find a friendly solution.
