So through the GUI if you invite users who have been part of the org recently, you get these options to reinstate privileges which is great

I checked the network tab and it makes a POST request towards
https://github.com/orgs/equinor/invitations?invitee_id=<github_id>&role=reinstate

This doesn’t seem to happen / be available when making the call through the API though
https://docs.github.com/en/rest/reference/orgs#create-an-organization-invitation

We tested removing a user, inviting them through the script. The invite works, but the privileges are not reinstated. The person had lost access to their repos + starred equinor repos (assuming this is because he lost repo access, assuming also access to Github teams etc.

Since this isn’t supported through the API call, I assume this also means that the SCIM provisioning which re-invites removed org members also makes them start fresh, which is sub-optimal for our use case.

I’ve also had reports earlier that re-instated members also have had their personal access tokens / ssh keys “lost”, which probably means they mean have been de-authortized from using SSO to the org. I have not verified if or when this happens myself.
