I don't have the RC2 or PRO 2, but there should be an icon on the left hand side of the screen with a circle and an arrow pointing up in the app flight screen.
Hold the button down for auto launch.
No sticks needed.

Good video, thanks for sharing! Well explained why LUT is actually a good thing😀. I've learned to grade D-log M using CST in DaVinci Resolve but applying DJI LUT makes it a simpler process with less Nodes.
