Is it possible to use an entire flow of Dev Portal by using Federated Identity Provider (for example, Azure AD B2C) without showing the "Sign-in with AAD B2C button at all"

I would like to use Azure AD B2C as the only login mechanism to the APIM Dev Portal. Currently that works by showing a "Login with AAD B2C button" and the user has to click that button to login.

This is fine but not ideal, I would like the login page to automatically redirect to B2C for login without showing the "Sign-in with AAD B2C button at all". This way users who are already logged in in B2C, will be automatically logged in in APIM Dev Portal as well.

Another way to achieve this could be to "trigger/simulate the Button click" automatically once the user goes to the login page. Essentially don't want our users to see that button at all.

Is this possible at all?

Start at the Dev Portal login page and inspect the existing “Sign-in with AAD B2C” button flow. Determine whether the page supports redirecting directly to Azure AD B2C, and define done as users reaching B2C without an intermediate button click and returning authenticated to the portal.
