Course lock mode for mavic air 2s on ios

i have a new dji mavic air 2s
it can be used with litchi, which is fine.
unfortunately i can not find the „course lock“ mode.
this mode i used often on my mavic air for taking videos.
is there any setting required to activate this mode?

For air2s, it simply does not exist.

You can Emulate course lock by setting up a mission with 2 waypoints:

2 waypoints? - the drone than flies straight from one point to the other.
there is no way to fly left or right - correct?

But you can yaw left/right with the left stick and tilt the camera with the tilt-wheel.
