How do I add other's, so they're be able to edit and work on an app

I am in a group project working with the Spotify API, and I need to share the project, is that possible. I figured out adding user accounts, but that seems to be a completely different thing, and means nothing in my plight

Spotify only provides the API and keys. You can share those keys with your team members.

You should choose a file sharing service or GIT platform to work together on the app yourselves.
