Need help with embedding javascript on website

Working on building a comment section on my website which the forum I have has a way to embed topics directly. I was attempting to paste this code in but have failed at each attempt.

I’m running into some issues with pointing a forum subdomain to my main website.

I pasted the html code directly into the iFrame embed that Wix offers in the elements but it doesn’t work. I just get a “refusal to connect” error.

Is there a way to add the code directly into Velo to get the code to work?

When I do paste the code directly into Velo it just shows “JSX expressions must have one parent element”.

Not sure how to go about connecting the javascript to the iFrame element. I’m guessing there has to be a parent. I’m guessing the code is the child element?
