F1 TV on a LG TV

Starting development on LG TV, need some help on how to start building the app that shows F1 TV on a LG TV.
Can’t find any information on how to do this.
When trying to use the sample HostedWebApp-main, just a simpel webbrowser it shows browser not supported. Is there any way to set the useragent string.

Or is there a other way on how to this?
