Kodi call method JSON?

[azure basalt]

I am trying to create a button to navigate up (amongst others) for my Elgato Stream Deck. I can't seem to figure out the JSON syntax to call Input.Up
It says this below the JSON box:
Available options
method (required) Name of the Kodi JSONRPC API method to be called.
Example: VideoLibrary.GetRecentlyAddedEpisodes

This doesn't really help https://kodi.wiki/view/JSON-RPC_API/v10#Input.Up

Figured it out {"entity_id": "media_player.coreelec", "method": "Input.Up"}
