Multicopter Simulation (ros2, gazebo garden)

hi, I have a setup with ubuntu 22.04, ros2 and gazebo garden.
setup working for single copter. before with gazebo classic and without ros, I have done multicopter simulations. with ros, I update the launch files, add a iris_1.launch.py, edit the world.sdf file, etc.

my problem is ı can not see ros topics from second drone.(ı can control both drones from mavproxy) ı do not know it is connected to ros or whatever. what should ı do?
