Subscribing to zed_interfaces ObjectsStamped.msg using Python subscriber

I’m using a Jetson Orin and ZED2 to do object detection using the ROS Noetic ZED wrapper. My ROS package uses Python scripts and I’d like to setup a Python subscriber to subscribe to the ObjectsStamped.msg message in the zed_interfaces package. We’ve tried to convert the C++ subscriber example to Python with no success importing the message. Does anyone have experience with this application and could help?
