I need a GitHub App to implement NixOS/nixpkgs#336261, because the standard GitHub Action tokens don't have sufficient permissions.

Instructions:

• Create new App (direct link)
  • Name: Nix Owners
  • Homepage URL: https://github.com/NixOS/nixpkgs
  • Disable Webhooks
  • Permissions:
    • Repository > Pull Requests: read-write (to request reviews)
    • Repository > Administration: read-only (indirectly needed to check whether a review can be requested)
    • Organization > Members: read-only (indirectly needed to check whether a review can be requested)
• Install the App on the NixOS, give it access to only https://github.com/nixos/nixpkgs
• Set the App ID as a new repository variable (direct link) named OWNER_APP_ID
• Generate a private key for the App and set it as a new repository secret (direct link) named OWNER_APP_PRIVATE_KEY
