I wish there was a way a group of gdevelop 5 users can create a game as a group while staying in different locations
This is up to game developer.In feature request group we ask developer for some feature.
There is a way. There are several ways, in fact.
Github is probably the best way for three persons and more.
You’ll find tuts on Google.
You can take a look on Properties of your game and set this option Project file type : By default, your game is saved in a single file. You can also choose to save it as a multiple files: each scene, external layout, external events will be saved in a different file. This is perfect for working on a large game in a team and sharing your game in a version control system like Git or Mercurial.
