Github Codespace manages what they call a Developer Container, which provides a fully featured development environment. Whenever you work in a codespace, you are using a dev container on a virtual machine.

As from documentation:

By default, your codespace is assigned a token scoped with read permission or read and write permission to the repository from which it was created

If your project needs additional permissions for other repositories, you can configure this in the devcontainer.json file, as described in "Setting additional repository permissions"

To set all permissions for a given repository, use "permissions": "read-all" or "permissions": "write-all" in the repository object (the .devcontainer.json file):

// .devcontainer.json
{
  "customizations": {
    "codespaces": {
      "repositories": {
        "my_org/my_repo": {
          "permissions": "write-all"
        }
      }
    }
  }
}

So, through the .devcontainer file one can setup a specific repository dev container to have the required authorization to pull and push it's project submodules repositories!
