ACF group and NinjaForm Post created

Hello,
I created a form with the NinjaForm plugin. This form generates a new post composed of ACF fields. For simple fields I have no problems I use:

// SUBTITLE FIELD
function subtitle_projet ($ field) {
  // only on front end
  if (is_admin ()) {
    return $ field;
  }
  if (isset ($ _ GET ['subtitle'])) {
    $ field ['value'] = $ _GET ['subtitle'];
  }
  return $ field;
}
add_filter ('acf / prepare_field / key = subtitle_1622456289725', 'subtitle_projet');

On the other hand, I cannot do the same thing for fields contained in a group (simple fields, repeater). Does anyone have any examples for me (repeater in group, subfield in group)?
Regards
