Subscribing to two or more distance sensors mounted on UAV model in SITL_gazebo simulation

Hi there,
I want to know how to subscribe to two or more distance sensors oriented in different directions on iris model in sitl_gazebo. Currently, I can get distance information from distance sensor Ided as 0. The rest do not display infos as i tried through “rostopic echo mavros/distance_sensor/<sensor_name>”. Thanks in advance
