How to access a Private PlayStore app hosted by another organization?

Samsung SDS has given us access to an application that they host in their Private Play Store. They have allowed our organization to have access via their Google Developer account settings but, I don't see a method for accessing/adding this to my App Repository in MEMDM Plus (Hosted/Cloud MDM). Any insight?
