popin mailchimp

Hello,
I have a site where I want to pop up or popin as soon as the visitor opens another tab or leaves a page of the site. Popup mailchimp display the newsletter registration display. I generated the script on mailchimp but it does not work

<!-- Début insertion pop-in mailchimp -->
<script type="text/javascript" src="// downloads.mailchimp.com/js/signup-forms/popup/embed.js" data-dojo-config="usePlainJson: true, isDebug: false"></script><script type="text/javascript">require(["mojo/signup-forms/Loader"], function(L) { L.start({"baseUrl":" mc.us14.list-manage.com","uuid":"e20dbdb8499262ba50c724c7b","lid":"41f0f6974e"}) })</script>
<script id="mcjs">!function(c,h,i,m,p){m=c.createElement(h),p=c.getElementsByTagName(h)[0],m.async=1,m.src=i,p.parentNode.insertBefore(m,p)}(document,"script","https://chimpstatic.com/mcjs-connected/js/users/e20dbdb8499262ba50c724c7b/09974d2a1a8a85e23e28785e7.js");</script>
<!-- Fin insertion pop-in mailchimp -->
