User groups in Adobe Sign

I have a bit of a tricky issue that I'm trying to resolve. Hoping that you all can help 🙂

I work in our IT Operations department and I recieved a ticket from a user saying that they need access to a "Treasury Compliance" group in order to use the associated shared templates. The thing is, we don't have a "Treasury Compliance" group anywhere. Not in the Adobe Admin panel. Not on our local AD domain. Not in Microsoft AzureAD. I haven't been able to find this group anywhere. 

Our users do not use any on-prem applications of Adobe. It's all cloud based.

What make this so odd is that we have users that are in this "Treasury Compliance" group but they can't invite or add anyone to it. I've confirmed this by remoting onto one of the member's computers. It shows on the shared template that it can be accessed by anyone in the "Treasury Compliance group" on the right side panel. I asked them if they know who the group creator is and they told me that she left a year ago. 

When I looked online to see if we could make a new group, Adobe's documentation looked like it's referring to account groups. Essentially groups to add accounts to so they can share products. Are these one in the same? What about just being in a group so you can share templates between each other? Will these people need to be set to the Group Admin role?

Any help would be appreciated. Thanks!
