As far as I can tell, there can be Installations on both Organizations and Users (both implementing the RepositoryOwner interface) In both cases, I’m using an Installation token as the bearer token on the v4 Graph request.
When listing the Repositories on an Organization Node-type the list is properly scoped to the selected Repositories of the Installation
However, listing the Repositories on a User Node-type the list seems unscoped to the Installation.
It would be useful to scope that list of Repositories to the Installation as well.
