I created a Cognito userpool and an Azure AD b2c application. I connected Azure AD b2c to Cognito as a OpenID Connect identity provider.
I am able to login successfully with an authorized user configured under my Azure AD. And if I log in with another Azure account from another directory, the page shows a proper message telling me my account does not belong to the Azure AD.

Instead, I was expecting a message like below
