How to get Web app id for webOS TV

Hi, I’m trying to pass a json file from an android application to the web app I’m developing for LG TV via connect sdk, but to proceed I need a web app id, but the reference url for webOS TV doesn’t work here. Does anyone know if it’s been updated somehow? or what if it works differently now and the documentation hasn’t been updated?
any suggestions are appreciated :grin:
Thank you
