How to set each rotor thrust

PX4 Autopilot
1

Hello, I am trying to set each rotor thrust for research objective, but something wrong with my PX4 6x settings.
I already set THR_MDL_FACto 0.7 in QGroundControl.
Firstly, I call publish_vehicle_command() and arm() like this.

this->publish_vehicle_command(VehicleCommand::VEHICLE_CMD_DO_SET_MODE, 1, 6);
this->arm();

After this setup, I call publish_offboard_control_mode() and publish_actuator_motors() in every control period, as follows:

void publish_offboard_control_mode()
{
    OffboardControlMode msg{};
    msg.position = false;
    msg.velocity = false;
    msg.acceleration = false;
    msg.attitude = false;
    msg.body_rate = false;
    msg.body_rate = false;
    msg.thrust_and_torque = false;
    msg.direct_actuator = true;
    msg.timestamp = this->get_clock()->now().nanoseconds() / 1000;
    offboard_control_mode_pub->publish(msg);
}

void publish_actuator_motors()
{
    ActuatorMotors msg{};
    msg.control[0] = 0.1; // example
    msg.control[1] = 0.2;
    msg.control[2] = 0.3;
    msg.control[3] = 0.4;
    msg.control[4] = 0.5;
    msg.control[5] = 0.6;
    msg.timestamp = this->get_clock()->now().nanoseconds() / 1000;
    actuator_motors_pub->publish(msg);
}

Is this correct method?
