AWS Cognito + ReactJS + Azure AD + SSO + Redirect URL handling

I am trying to find a test project in ReactJS runs and SSO's an user with Azure AD that links to AWS Cognito.

For example, how do I get users to show something like a Hosted UI that they sign in to Azure AD and then Redirect them back to ReactJS to extract the token.

Its very hard to find a test project, as I did see Amazon Amplify, but nothing specific.

Does anyone have any test projects to share please..
