CAM_TRIGG_DIST missing in the Full Parameters list?

I was going through a tutorial and got the camera going etc. But on the step where i setup the CAM_TRIGG_DIST in the Full Parameters list i search for it and cant find it.

I might be out of touch but not sure if anything changed related to this parameter. What i want to do is set the distance to 1 meter so that i can test the camera takes pictures based on the distance which will be triggered when i set it to 1 meter.

When i search with “cam_” these are the only parameters i see…CAM_TRIGG_DIST is missing.

CAM_DURATION
CAM_SERVO_OFF
CAM_SERVO_ON
CAM_TRIGG_TYPE

what firmware did you have loaded?
