Helpful mods for collaborative module building?

Good morning. I was wondering if any of you happened to have any experience with collaborative campaign/adventure building in Foundry, and if so, what (if any) modules did you use that really helped with the “collaborative” aspect of it?

Regardless if it’s for journal entries, asset creation, compendiums, whatever - I’d like to hear about it and how it really helped you and your team create together.

Thank you.
