body: <p>I have a mutation named <code>deleteSong</code>. I was wondering after the mutation has passed through how can I pass multiple queries into <code>refetchQueries</code>?</p>
  
  <pre><code> this.props
    .deleteSong({
      variables: { id },
      refetchQueries: [{ query: fetchSongs }] //&lt;-- I only know how to pass 1 query
    })
    .then(() =&gt; {})
    .catch(err =&gt; {
      this.setState({ err });
   });
