two lasers and the same pointcloud frame_id

[ctub]

Hello, I have two MID-70 Livox lidars and i am using the config file such as { "lidar_config": [ { "broadcast_code": "3GGDJ7N00100561", "enable_connect": false, "return_mode": 0, "coordinate": 0, "imu_rate": 0, "extrinsic_parameter_source": 0, "enable_high_sensitivity": false }, { "broadcast_code": "3GGDJ7U00100571", "enable_connect": false, "return_mode": 0, "coordinate": 0, "imu_rate": 0, "extrinsic_parameter_source": 0, "enable_high_sensitivity": false } ] }

Both generated pointcloud topics have the same frame_id. How can I get different frame_id?
