body: <p>There is some information <a href="https://jupyterlab-code-formatter.readthedocs.io/en/latest/how-to-use.html#changing-default-formatter" rel="nofollow noreferrer">here</a>, but it's not clear where to put the code.
  My main task is to use black or autopep8 formatter for the whole notebook</p>
