IMPORTANT: This feature is only supported on iOS and Android and must be bypassed if the asset is loaded to myINTERACT Desktop.

To force enable the back button in an asset that links to video files please implement the following script

<script type="text/javascript">
function forceEnableBackButton() {
document.location = "ni-action:enableback"
}
</script>

The HTML, ensure that you add this to the <body> tag
