Can addons load 3rd party iframes with enabled JavaScript?

My “Web Translate” addon loads full translator page (Google, DeepL, Bing, etc…) into “iframe” inside popup window (or injected into the page as iframe).

But today it was removed from the store due to:

Sandboxed iframes with attributes ‘allow-scripts’ and ‘allow-same-origin’ are not allowed for security reasons. Please remove them.

But if I remove “allow-scripts”, that would load the translator page without javascript and none of the translators will work without javascript:

What can I do fix it?
Is there a way to load iframe with javascript enabled?
Thanks!
