How to use the quantuminspire.credentials.load_account function in quantuminspire

project_name: The project used for executing the jobs.
            coreapi_client_class: Coreapi client to interact with the API through a schema.
                                  Default set to coreapi.Client.

        Note: When no project name is given, a temporary project is created for the job and deleted after the job
              has finished. When a project name is given, a project is created if it does not exist, but re-used
              if a project with that name already exists. In either case, the project will not be deleted when a
              project name is supplied here.

        Raises:
            AuthenticationError: An AuthenticationError exception is raised when no authentication is given
                                 and the token could not be loaded from the default location.
            ApiError: An ApiError exception is raised when the schema could not be loaded.
