SLAM odometry message type

Hello,

I want to subscribe to odometry publisher of the elbirus slam gem as described in:
https://docs.nvidia.com/isaac/isaac/packages/visual_slam/doc/elbrus_visual_slam.html

However, in the tutorial described the name of the publisher, left_camera_slam_pose, but not its type of message.

Can you help me to find the type of the message the publisher use for publishing pose?

Thanks in advance

The type of the proto is Pose3dProto.
