How to share a collection with my friends with active syncing?

Hello, I am currently working at an anki flashcards database that I want to share to my friends, but it isn’t finished. I want to share the collection with my friends as they could sync the collection after I add new cards without sending the file each time I add a new card. How could I do this?

I don’t think the functionality is implemented into Anki. You would need to use an add-on like Ankihub or AnkiCollab to achieve that.
