The export button is not there (world menu's), but the export was in the in game setting (play the world you wanna export first and you can see the export there). I tried doing that but the file has no content and has no progression for some reason. When doing this I see a glimpse of a notice saying "do not-" and then force that notice close making it unreadable.
*EDIT after different approach I made the export world work. I just disabled the resource pack in the specific world and only activate it in the global resource pack and somehow it worked I guess.
