Describe the problem caused by this bug

When the user lands on the login screen, the button to get redirected to an external SAML identity provider is not rendered.

This only happens when the new login UI is selected for that particular application, when the new login UI checkbox is disabled, the button is shown as expected.

To reproduce

1. Create a new application inside your project, and turn on the toggle called "Use new Login UI"
2. Create a new external IDP SAML integration inside identity providers and enable it
3. Navigate to the login screen by sending a request to /authorize
4. In this case, the button to use that external SAML IDP is not rendered
5. If you turn off the toggle from step 1, and repeat the steps, the login button will be rendered.

Screenshots

Expected behavior

The button to continue to the external SAML IDP should be rendered regardless of the logni UI checkbox selection.

Hi @fcoppede, Can you recheck the IDP settings please? The login shows the primary organizations IDPs and not the instance default if no other context is provided via OIDC scope or query param. To me it appears to be rendering just fine. IDPs must selected activated as well to appear in the list.
