Would I able to load a Gazebo world as a training model into rlSimulinkEnv function ?

Hi, I'm trying to use  Simulink to apply turtlebot3 to do deep reinforcement learning simulation, the tutorial I'm following is from Robotics Arena DRL for Walking Robots. I face a problem is that I want to load the Gazebo model such like turtlebot3_world.world instead of the walking robot model, but I didn't find any tutorial about it. Here is the code at the file createWalkingAgent2D.m % Environment mdl = 'walkingRobotRL2D'; load_system(mdl); blk = [mdl,'/RL Agent']; env = rlSimulinkEnv(mdl,blk,observationInfo,actionInfo); If there is anyone knows it, please give me some advicess. Thank you!!
