How to display a message about successful submission of forms in Bitrex?

Question

1C-Bitrix

In the form settings there is a macro "SUCCESS_URL" => "" , in which we can specify the page to which we will go in case of successful submission of the form.
But how to make it so that after a successful submission we would not go to the page, but would display a message about the successful submission as well as an error message?
PS: I am using ajax form processing.

Answer 1

To display a notification, you need to register in the form template<?=$FORM->ShowFormNote()?>

Answer 2

Do not specify this URL, then a message will be displayed after reloading the page. There is a message output in the standard form template
