teleop gripper issue in humble-devel.

[Eunsunggcu]

I want to control open manipulator 6dof in ros2 humble.
so I got the source code of open manipulator 4dof (branch:humble-devel) and tried to change it.

and i realize that teleop in humble-devel branch, there is nothing about gripper operation.

but i see that part of teleop in foxy-devel.

Is that any reason about this difference between those two branches?

It will work if you add the program related to gripper as shown in foxy-devel. Note that there is no send_tool_controll_request function.
