How to display third party js in DLE 14.1 news?

Question

JavaScript

I spent a lot of time and could not display the following code in the site news on DLE 14.1:

<div id="cm-osago-check-iframe" data-webmaster-id="X8Ro0x"></div>
<script src="https://cpamotor.ru/js/osagocheck.js"></script>

I tried to do it through add. fields according to this instruction: tehnopost.info/retseptyi/81-vstavit-skript-v-novos...

I only achieved that I can display a line in the source code of the page.

The goal is to get such a widget at the right place in the news, or at least at the end of the news.
