I am trying to build a ROS2 node in Matlab that is compliant as a life cycle managed node. I am having trouble understanding how to setup the node state machine and a ros2 service callback function for a state transition of that node. I know that lifecycle_msgs are supported with R2022b, so presumably someone at Matlab has done this. If you have example code on how to build the node's state machine and state transition callback function, I would love to see how this is done.
Thanks.

Hi Michael,
Currently, ROS Toolbox does not support this capability. Team is actively working on this feature. This will be available in the future releases of ROS Toolbox.

@Jagadeesh Konakalla Thanks. Does Mathworks have a out-facing roadmap for planned ROS2 feature support? It would help users know when certain primary features like this, parameters, more recent version (Galactic, Humble), etc. will be supported. I'm sure there is an internal plan. I doubt it is or will be released to the public, but I thought I'd ask anyway.
