Executing a remote js file

I’m trying to embed a Webex meeting widget into a survey.

The code for loading the widget is comprised of a 5MB, minified, obfuscated JavaScript file, with some base-64 thrown in.

If I simply paste the whole thing into my question’s JavaScript entry field, the validator won’t accept it. The general guidance I’ve seen online recommends inserting a script tag into the DOM, but if I do that it doesn’t execute. Perhaps this is a result of a safety feature built into Qualtrics?

I’m beginning to suspect it can’t be done.

Has anyone here done anything similar? Does anyone have any ideas?

Thanks in advance!
