Moveit 320 M5 gripper opening/closing

[Milk-tea-Taro]

I want to pick and place blocks with gripper
Do you have gripper opening/closing code?
I tried but it just works in "roslaunch", not in "rosrun".

First run the corresponding launch file, and then use rosrun to run the following program to control the gripper to open or close: https://github.com/elephantrobotics/mycobot_ros/blob/noetic/mycobot_320/new_mycobot_320/scripts/mycobot_320_gripper_slider.py
