    This will allow users to list all owned workflows by default. Optionally, a
    user can provide a workflow name (unique with respect to a user) to
    list all versions of the specific workflow.

    Args:
        wf_name: The name of the workflow.

    Example:
        >>> get_wf("wf.__init__.alphafold_wf")
