Load SSO page when setting up OAuth authentication

Hi,
I was wondering if it is possible to give a user the SSO page when setting up the OAuth authentication. I followed this very clear guide (thank you Qualtrics!): https://api.qualtrics.com/api-reference/docs/Instructions/oauth-authentication-authorization-code.md
and managed to set it up which nicely results in the following screen:
When you click on 'Sign in with SSO' users will get asked their organization ID before logging in with their SSO. Is there a way for me to do these steps for them? So redirect them immediately to the SSO page of the uni, because I know the organization ID but not all teachers know the organization ID resulting in a lot of questions. Thank you!
