We were thinking on using Azure B2C but we ran into limitation where B2C does not support on-behalf of flow. API generating token on users behalf is very critical for some integrations. Since B2B can also store external users, i would like to know:
1. Is it a good strategy to store external user in B2B?
2. Will B2B support on-behalf of flow?
Any other suggestion that would allow us to use Azure B2C but support on-behalf flow?
