How to let users create game content

I have added a way for custom content to be loaded into my game using Data Assets.

I currently have a DLC for my game that uses it and I am building inside of the game.

My question is how do I allow users to make content for the game to load. Do I need to give them access to the full project to do so, or is there some other way. Loading UGC doesn’t make much sense to do if the users aren’t able to generate that content.

I haven’t seen much online about a way to give users tools to make content to load. Any help would be greatly appreciated
