We should provide information to our developers who could not react to the org invitations in time how to ask us to link the placeholder accounts to their real github account later.

Our org admins could then use this workflow (as per our github contact):

Mannequin related functionality is in our GraphQL API.

I’d recommend using the CLI for one of our modern migration tools, which has some built-in functionality for managing your mannequins: https://github.com/github/gh-gei

The docs here explain how the CLI works: https://docs.github.com/en/early-access/enterprise-importer/completing-your-migration-with-github-enterprise-importer/reclaiming-mannequins. In short, you can generate a CSV with a list of all of your mannequins, fill in the names, and then send the invites.
