[APP] LG ThinQ - Meet LG ThinQ, the finishing touch on your smart home. (by LG Electronics)

Anyone used the ThinQ App to control an LG TV. How do the flow cards work that 1. Launch Application, 2. Switch to Channel, and 3. Set TV Input work. I would like to confirm that using one of these 3 flow cards that I can select TV or HDMI port as the input, Change the TV channel if TV input selected, or select Youtube, Disney etc using the Launch Application flow card.
Could someone please confirm or correct me.
