GravityView - Remove required fields from Edit Entry

gravityview-edit-entry-unrequire.php

<?php

add_filter( 'gravityview/edit_entry/form_fields', 'gravityview_edit_entry_dont_require_fields' );

/**
 * Remove the "required" setting from Gravity Forms fields in GravityView Edit Entry
 *
 * @return GF_Field[]
 */
function gravityview_edit_entry_dont_require_fields( $fields ) {

  foreach( $fields as $key => $field ) {
    $field->isRequired = false;
    $fields[ $key ] = $field;
  }
  
  return $fields;
}

I'm not skilled enough to analyze the code above, but do you know if this has been updated? I have this added, but it's still requiring fields when I try to edit entries. thanks!
