Deeplinking for LG TVs

[March4ND]

We're looking to deeplink from our own Smart TV application to Spotify's on a WebOS LG TV. This is possible with WebOS, but we need Spotify's application ID to check if it's installed and then to direct the user to the app, ideally to our playlists. Does anyone know the application ID for this? We've managed to find different application IDs for Spotify's LG app, but none seemed to return a positive result on checking if it was installed despite being installed.
