The world folder, typically named “world” sometimes along with “world_nether” and “world_end” are (obviously) the world stuff, and is all you need for importing a world. If you already have a working server and would like to use that world instead, you have 3 options:
Delete the existing world folder(s), and replace it with that one
Rename the existing world folder(s) to something else, and drag the new/old world folder in
Drag the existing world folder in, followed by changing the level-name in the server.properties file to match the world’s folder’s name.
Note: The world that you’d like to use has to have it’s folder named “world” unless changed in the server.properties file; if changed there then the world must match whatever’s there.

Moved this zip to imports, it showed up in the UI, pressed import, set a port and a profile for it and i just got a vanilla MC world.
So you have a working server, now you either just have to delete the one generated by the server and rename the one you want in it’s place, or change level-name
in server.properties
to match the world folder.
