entity_get_form_display($entity_type, $bundle, $form_mode)
Returns the entity form display associated with a bundle and form mode.
The function reads the entity form display object from the current configuration, or returns a ready-to-use empty one if no configuration entry exists yet for this bundle and form mode. This streamlines manipulation of entity form displays by always returning a consistent object that reflects the current state of the configuration.
Example usage:
Set the 'body' fiel
