Magento 2: issue with external call javascipt

I’ve created custom .phtml file in app/code/Trustmate/Opinions/templates/trustmatewidget.phtml

Here I add short link to .js code called code from url with reviews slider on bottom page.

Then I created a new block:

<p>{{block class="MagentoFrameworkViewElementTemplate" template="TrustMate_Opinions::trustmatewidget.phtml"}}</p>

Now I referesh page. The widget appears on the frontend, but there is a some conflict with javascript throughout the store. Example no load slider products etc.

But this is very strange: I refresh page and one time work, and then in second refresh no work.

Depending on the refresh, sometimes it is possible to load correctly all the js elements of the page and sometimes there is a problem as shown in the attached screenshots. Js console points to

Uncaught TypeError: wrapper.wrapSuper is not a function
