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?
