Is it possible to use JS to hang a listener when sending it for validation?

[user62bc8073ba4a4804 (Mary Marnell)]

I have AJAX form [gravityform id="2" title="false" description="false" ajax="true" required_legend="false"]
I need to run a js function after submitting a form when the form shows the message gform_validation_errors . Is it posiable?

I need something like that -

$(document).on('gform_post_validation', function(formId, isValid) {
	if (formId === 2) {
		console.log("Form ID 2 validation result: " + isValid);

		$('.gfield_contains_required input').each(function() {
			let $label = $(this).closest('.gfield_contains_required').find('label');
			if ($(this).val().trim() === '') {
				$label.addClass('hidden');
			} else {
				$label.removeClass('hidden');
			}
		});
	}
});
