stopPropagation for HTML elements with iframes?

Hi, new to Velo/Wix API in general and all of my JS solutions are being turned down. I want to remove any click through action on my HTML elements that contain iframes without using something like pointer-events=none because there are other user actions I still want to function.

Why? I am embedding display banner ads I have worked on and want the viewer to interact with the ad (mouse handlers, nav arrow clicks etc) but not to actually link through to the brand/client page while on my portfolio page. Any help would be very welcomed!

Follow-up Edit:
I have tried adding sandbox to the iframe tag but unfortunately it flags some elements of the ads as “pop-ups” (due to the ad origin’s config which cannot be worked around) and dumps those elements. It worked otherwise but can’t be a solution for this issue.
