Increase motion information sensitivity of DF robot c1001 mmwave sensor

Hi. I am using the DF robot c1001 mmwave sensor for fall detection. I am using their library available on the github https://github.com/DFRobot/DFRobot_HumanDetection.git. There are methods using which I can change the sensitivity of the fall. I also want to change the sensitivity of the human motion information. For example currently I am sitting on a chair in a still position and the sensor is showing “still”, when I use my phone, My body is still not moving but the fingers are moving, now I want the sensor to show “Active” since my fingers are moving but it is showing “still”. I want to know that is there any way to increase this sensitivity because I cant find any method in the library to do this.
