Short question about the experimental trajectory setpoint

Hi,
I am currently working on my masters thesis about detect and avoid systems that are based on the panel method. Opposed to other algorithms for path planning in DAA systems this method does not compute waypoints to follow, but yields a velocity vector. When browsing through the px4-ros2-interface-lib (GitHub - Auterion/px4-ros2-interface-lib: Library to interface with PX4 from a companion computer using ROS 2) I came across the “TrajectorySetpointType” which consists of a 3dimensional vector. I am writing this post, to be absolute sure that this setpoint type enables me to command a velocity vector at a certain rate.
Thanks for your help!
