Control 2F Gripper in Gazebo

[fwarmuth]

Hey,
i am try to get a Gazebo simulation running with a 2F-140 gripper attached to a UR10e. I got the same setup in real life but want to create a digital twin for testing.
I cant find any documentation how to control the gripper within Gazebo?
Any hint?
Also in real life i am struggling the the ModBus forwarding, to MoveIt or just direct control - but lets start with Gazebo.
While this fork seems be worked on, their might be people who can point me in the right direction?

So issue is:
how do i control the simulated 2F gripper with a Python node?

Regards!
