Can i send data to an Unreal Engine animation using Javascript?

Hi

We’ve created a web page product configurator in html/javascript. It uses checkboxes and questions in modals to help to configure the sensors required in an instrument.

We want to have an Unreal Engine animation of that instrument on the web page and pass variables/data to it from the javascript in the configurator/web page. Is this possible to do client/browser side without any browser plugins (web page needs to be used by the general public without browser mods)?

TIA,
Chris
