load/use jQuery time ago in theme

I’m trying to use the great timeago plugin from https://timeago.yarp.com/ in my theme.

I’ve added this to my functions.php file

function wpb_adding_scripts() {
wp_register_script('jquery_timeago', plugins_url('/js/jquery.timeago.js', __FILE__), array('jquery'),'1.1', true);
wp_enqueue_script('jquery_timeago');
}

add_action( 'jquery_timeago', 'wpb_adding_scripts' );

then at the top of the template page I’m adding

<script type="text/javascript">
jQuery(document).ready(function() {
  jQuery("abbr.timeago").timeago();
});
</script>

and where I’m testing it in the body of the page I have

<abbr class="timeago" title="2007-07-17T09:24:17Z">July 17, 2007</abbr>

which is copied from the example on the website.
