Trouble connecting Unity and Matlab using ROS2

I am trying to establish the connection between Matlab and Unity using Matlab's in-built ROS2. However, it seems like the tcp_endpoint node is not getting activated. I was able to do the same with ROS though.

To start the tcp_endpoint node I am running following commands.

pyFile = fullfile(matlabroot,'sys','ros2',computer('arch'),...

'ros2','lib','python3.9','site-packages','ros_tcp_endpoint','default_server_endpoint.py');

[status, msg] = ros.ros2.internal.runros2cmd(['python ' pyFile ' &']);

Unity is set to ROS2.

After these steps, when I run ros2 node list I do not see any running node.
