Could you please add an ID (like btn-azure-ad) or a class (btn-azure-ad) to the “Sign-in with Azure AD” in the login page?
Otherwise, its hard to target this button with the selectors given their generic classnames btn and btn-default. This is quite important because we need to show or hide this button programmatically based on other parameters. With the generic classnames, a wrong button could be targeted instead.
E.g. The “Login” button is aptly named the “loginButton”.
