Pre-select a single social connection to skip Auth0 login for New Universal login

[lightenna]

I’m trying to set up Auth0 for my SPA authentication. I have a single social connection (GitHub). GitHub is the only option, because all users will need accounts that can host git repos. I’m interested in GitLab, but I understand that social integration is not currently available.

Currently users are presented with the New Universal Login with a single “Continue to GitHub” button. I’m trying to improve the user experience. I understand historically it was possible to skip this step by passing connection: 'connection-name' to the loginWithRedirect call.

In 2019, the topic was covered for an old version (I think the ‘classic’ universal login):

How to skip aut0 login page and directly redirect in to social login site?

hi , is it possible to skip authO login page and directly navigate to gmail or facebook page? if yes plz tell me. the current process is myApp=>authO Login page=>social web site login page=> Back to my App (if successful login page) i want to skip authO login page .

This does not seem to work any more for the New Universal Login. Several of the links in that thread are now dead, which is making it hard to confirm my suspicions:
https://auth0.github.io/auth0-spa-js/interfaces/redirectloginoptions.html#connection

Please could someone confirm my assertions above and offer any guidance on how to implement this, or when the New Universal Login will be a feature-complete replacement for the Classic Universal Login?
