Unable to integrate Tawk.to in the ionic app

ionic-v1
1

I am trying to integrate the Tawk.to javascript widget in my ionic app. But i am not able to see any widget by default.

<!--Start of Tawk.to Script-->
 <script type="text/javascript">
var Tawk_API=Tawk_API||{}, Tawk_LoadStart=new Date();
(function(){
 var s1=document.createElement("script"),s0=document.getElementsByTagName("script")[0];
s1.async=true;
s1.src='https://embed.tawk.to/5968515a6edc1c10b0345ef8/default';
s1.charset='UTF-8';
s1.setAttribute('crossorigin','*');
 s0.parentNode.insertBefore(s1,s0);
})();
</script>
<!--End of Tawk.to Script-->

Seen that. But, it’s still not working on a device. It works on ionic serve.Does anyone have a sample project
