Publish posts automatically

Hello! I used the hook to publish automatically products when the form is submitted. But it does not seem to work. Here is my code :

add_filter( 'cf7_2_post_status_product', 'publish_new_product',10,3);
  /**
  * Function to change the post status of saved/submitted posts.
  * @param string $status the post status, default is 'draft'.
  * @param string $ckf7_key unique key to identify your form.
  * @param array $submitted_data complete set of data submitted in the form as an array of field-name=>value pairs.
  * @return string a valid post status ('publish'|'draft'|'pending'|'trash')
  */
  function publish_new_product($status, $ckf7_key, $submitted_data){
    /*The default behaviour is to save post to 'draft' status.  If you wish to change this, you can use this filter and return a valid post status: 'publish'|'draft'|'pending'|'trash'*/
    if ($ckf7_key == '4022' || $ckf7_key == '6459'){
		return 'publish';
	} else{
		return $status;
	}
	
  }

I use the form ID as $ckf7_key, is that the problem ? I could not find the form KEY.
