DiscourseConnect Provider Questions

what did you mean by this?

So I just tested this. I took an account that exists on Discourse but not on Wordpress and tried to login and WP gave the following errors:
Screenshot 2023-07-01 220001
Screenshot 2023-07-01 220024

Which I guess makes sense from WP perspective since the user doesn’t actually exist on WP.

The question is: would enabling DiscourseConnect Provider mean that existing Discourse users, that are not registered on my WP, can’t log in anymore?
Is there a solution to this?
