Creating SSO app for Blackbaud through Azure AD

Sorry if this is the wrong place to post this. I'm trying to create an SSO app for our students through Azure AD. I have it set up so whenever a user clicks on the link, it sends them to the login page. The problem I'm having is that it doesn't automatically sign the users in, they have to manually click the ‘sign in with Microsoft’ button (which does work) and sign in with their Microsoft credentials again. After speaking with Microsoft support, they said I did not have the right redirect and sign in urls for the app. Would someone know what the right urls would be? Has anyone ever successfully setup SSO through Azure AD with Blackbaud?
