AWS Cognito / Azure AD B2C authentication with Appian application.

Has anyone tried or any references available on how to integrate / authorize identify brokering and social media login to access appian application.

Example use case, User does not want to register, just need one time temporary access to appian application.

We can use use AWs Cognito OR Azure B2C for oauth / SAML based federated social logins, however we don't prefer to keep temp user accounts pool to activate / deactivate appian account OR increase the user account creation for each temporary login request.
