Postman Git Integration: How only save collections in rep?

I’m just starting with Postman and I’m trying to have it connected with my Repo in Azure Devops.

So far I have only created stand alone collections and have been doing manual exports.
I saw Postman allow to connect to Azure DevOps but I was only able to do it by creating an “API” and then include (duplicate) my collection.

Is this the only way? Can I not just “connect” the collections, environments and global variables?

Best Regards,
