Enabling SSO in enterprise affecting org owners inviting external collaborators

How does enabling SSO in our enterprise affects org owners ability to invite external collaborators ?

External collaborators do not fall under SSO for GitHub Enterprise Cloud.

Even repo owners, if allowed by org policy, can invite external collaborators.

Yes the last one i blocked. Only org admins should invite external collabs so i have less people to educate about governance or we have a wild wild west
