UE5 - How to change Epic Launcher project directory

I compiled the source code from github and used from binary


Now still, it shows that I don’t have any unreal version installed on epic launcher and on marketplace it doesn’t see that I have any projects, I cannot download assets because it requires a project to add the asset to, and it cannot see any project.

And yes, I clicked on show all projects,

So, how to change epic launcher 's projects directory or to download assets offline without installing useless version from the epic launcher

I am looking for a way to achieve that from within Unreal / Epic Launcher without moving the project to documents or linking the directories
