cf.get_position() in simulation

We would like to use get_position() in the simulation. However, we are currently unable to use this function. Is there a way to use this feature of crazyswarm2. The crazyswarm2 website says this function is not available for simulation. Can we activate this function by configuring the related scripts? We would like to test our swarm scenario in the simulation environment first.

Note: This function was working with crazyswarm1 properly in the simulation.

Update: The terminal shows all position data are zero:
