MODX REVO AjaxForm how to show the word SENDING.... when submitting?

Question

MODX

Friends who are familiar with AjaxForm in MODX? Which sends AJAX forms to the site. Please tell me how to do something that would show some kind of animation or the word

SENDING when sending a letter... thinks before receiving the server response. How to catch this moment in order to hang an animation on it, I can easily do this, I don’t know what event to hang it on, please help!!!!

This is how I do it, but nothing really works, this is not the right direction :(

$(function() { 

$(document).on('af_complete', function(event, response) {

console.log(response);

if(response.success != false && response.success != ''){
$(".loader").css('display','block');
}
});
  
});
