Move robot Container to location of Gripper

I added a custom gripper to a Generic Articulated robot, and I want to pick up things with this gripper.

So, without the added gripper, I can pick components off a Conveyor just fine.

When I add the gripper, I make a new Link in robot, add gripper geometry, and make a new frame “GripperTCPFrame”. Then I move robot GraspContainer to this new Link, and CHANGE the Location of Container to GripperTCPFrame.

Now, the robot moves the gripper over Conveyor, but upon signal to grasp, the component is not grasped.

So, what is the right way to change the LOCATION of where the GraspContainer detects objects ?

Thanks and best regards,
