Assigning AD group to Business Role via API

Looking for information on assigning AD Groups to a Business Role via the API.

I think I may have found the correct assignments table but I cannot seem to get it to work: OrgHasADSGroup

I have tried using it both ways with Group / Role (Org Tree) like so, nothing seems to work.

Body: {
"Members": [

Getting nothing assigned no matter what:
