How to change default map in UEFN?

Like the title says. Somehow I managed to great new map on top of the map that was default. Now I have made alot of changes and edits to. The non-default map is playable. Is there some way to change the default map in UEFN? Or do I even need to worry about it? Will my default map affect my playable map minimap etc?

Open the GameFeatureData (Project folder) asset and change map in it.

Please provide a screenshot? I need to replace my project level with a level backup
