Implement tawk.to livechat widget into ebay description

I need to implement [login to view URL] widget into our ebay description as a direct type in field. <!--Start of [login to view URL] Script--> <script type="text/javascript"> var Tawk_API=Tawk_API||{}, Tawk_LoadStart=new Date(); (function(){ var s1=[login to view URL]("script"),s0=[login to view URL]("script")[0]; s1.async=true; s1.src='[login to view URL]'; s1.charset='UTF-8'; [login to view URL]('crossorigin','*'); [login to view URL](s1,s0); })(); </script> <!--End of [login to view URL] Script--> Important ebay has some rules about meta and javascript.
