Is there any way in ACUL to get a button from the existing SAML integrations

Hello,
I’m looking for adding the external links in buttons like the ones showing in my standard universal login screen but into the ACUL signup and login screens that I have customized |

I have been searching in the documentation on how to do it but I still can’t find it, do you have any guidance?

I’m referring to the buttons for SAML integrations that are currently displaying in the default login and signup screens.
