Does this repo use private sources?

AADSTS50020: User account 'email@domain.tld' from identity provider 'live.com' does not exist in tenant 'Microsoft' and cannot access the application 'd5a56ea4-7369-46b8-a538-c370805301bf'(Azure Artifacts) in that tenant. The account needs to be added as an external user in the tenant first. Sign out and sign in again with a different Azure Active Directory user account.
