Is there a way you can give another person access to edit a collection

[RoyalZSZ]

So basically as the title says  Is there a way you can give another person access to a collection?

I'm making a workshop collection, and my friend wants to help but I can't give him access to edit. So is there another way I can give him access to edit the workshop collection?
Thanks in advance
