Why does js click function run multiple times?

I’m creating some accordion functionality for fields and paragraphs using a combination of twig templates and a custom JavaScript file.

Everything prints as expected and the basic accordion functionality works; however, the click function script is running multiple times, causing an “expand-collapse-expand-collapse…” behavior. See image:

Here is the script file:

(function($, Drupal) {  /* Add span to wysiwyg button classes for alignment ------------------------------------ */ Drupal.behaviors.accordionFaqFunction = {   attach: function (context, settings) {         $('.toggle').click(function(e) {                  e.preventDefault();                 var $this = $(this);                  if ($this.next().hasClass('show')) {                         $this.next().removeClass('show');                         $this.next().slideUp(350);                         console.log("hiding");                 } else {                         $this.parent().parent().find('li .inner').removeClass('show');                         $this.parent().parent().find('li .inner').slideUp(350);                         console.log("showing");                         $this.next().toggleClass('show');                         $this.next().slideToggle(350);                 }         });     } };  })(jQuery, Drupal);

Why is the script running multiple times?
