How to get a rendered views field value programmatically?

Yes, I see there are many answers already posted here and elsewhere for this; but sadly they are all wrong. These answers include any of the following:

$view->style_plugin->getFieldValue($rid, 'field_myfield');

foreach ($view->result as $rid => $row) {
 foreach ($view->field as $fid => $field ) {
   $values[$rid][$fid . '-value'] = $field->getValue($row);
   $values[$rid][$fid . '-render'] = $field->render($row);
 }
}

$views->_entity->...

or a few others. These are all returning the field of the base entity returned by the view. These are entity field values. These are not the "fields of the view".

I know how to access these in a twig template (views-view-fields--[viewname]--[displayname].html.twig) but haven't been able to find out how to do this in a custom module.

Answer:

From @4k4's tip below:

This works:

foreach ($view->result as $rid => $row) {
  $type[$row->nid] = $view->field['my_views_field']->advancedRender($row)->__toString();
}
