Using Social Media OAuth 2.0 with OpenID Connect for AWS WorkDocs Authentication

Hello AWS Community,

I am an AWS Solution Architect working on a project to build a portal for a small B2B Business Process Outsourcing (BPO) company. Our users are small businesses that primarily use social media authentication. We are considering AWS WorkDocs as a solution for our users to share their documents with the BPO company.

I have a few questions regarding the authentication process:

1. Is it possible to use social media OAuth 2.0 with OpenID Connect for authentication with AWS WorkDocs? If so, could you provide some guidance or resources on achieving this?
2. Can AWS Directory Services be federated with AWS Cognito? If yes, could you provide some insights or resources on how to set this up?

Any help or guidance would be greatly appreciated.

Thank you in advance for your assistance.
