I need to be able to grant access to the Forms Service API using Bearer Tokens obtained from our Azure AD instance.  I've been able to convert authentication for CMS and Content Delivery API but I can't find how to set this up for FormsServiceAPI.  I'm guessing that I need to somehow make the FormsServiceApi aware of Azure Ad so it we can validate those bearer tokens.  Can someone point me to direction on how to set this up?  We're using CMS (11.20.x) with .Net 4.6.2.  Thank you.
