How to set and get parameter values using the PX4-ROS 2 Bridge

I’m trying to read and set parameters values using the PX4-ROS 2 Bridge. But I cannot find any uORB topic that does that.

That does not exist yet in PX4. A client-server approach is required to be implemented, which means adding a new module or extending the param library to allow parameter requests through uORB. I have that on my backlog but no ETA yet. So any contributions in this regard at this point are welcomed.
