Does Web Browser Plugin works with HTML5 packagin?

Hi there I have created a project(sample one)

My Project Goal was to show a live stream feed from Youtube/Vimeo however web browser is the only way I can see
that will launch a site inside the game the project works fine when I am clicking on play. However after packing it to an HTML5 the game crashes and saying some uncaught errors is it really possible to do this if not what are the ways?

or is there any better way to do this?

I’m having a similar issue. Have you had any progress?

Same problem, any progress on this topic?
