How do I collaborate online with team members?

Hello. I’m running into issues with understanding how to collaborate with team members online on the same project. Can someone point me in the right direction? I know that Multi_editing is a thing in Unreal, but how to use UGS is something that the Documentation fails to explain how to navigate to. I’m kinda being pulled in different directions trying to understand how to set it up. Any assistance would be wonderful. Thank you.
