I have done this for a client using a custom API and made it part of the user journey, it used the Graph API to get info from Tenants. There are two groups available - the groups within the Azure B2C Tenant and the groups within the Azure AD Tenant that owns the Azure AD B2C Subscription (The business tenant). The API accepts a few variables, one of them being a groups attribute and the other being a tenant id attribute. If the user journey needs groups, it will add the group request, but needs the source, the attribute being B2C or Azure. They needed this to display certain applications on their portal based on group assignments. The Groups attribute is sent in the claims information and the portal app determines App display via the groups attribute information
