Is it possible to have UI controls (like sliders) for a C++ JIT process?

In Javascript processes, you can add different “controls” to the process like FloatSlider or Toggle as mentioned in the “Controls” section of the docs on javascript: Javascript | score documentation

However, I couldn’t figure out how to do this using the C++ JIT process. I’ve just been looking at the code in ossia/dataflow/nodes of libossia to get a feel for how these JIT processes are supposed to work, but none of the graph_nodes in that folder seemed to display UI controls when I used them in a JIT process. They obviously show up with a green port for each input, but nothing I can control with sliders or textual input. Is doing this like how it is done in a javascript process possible for JIT processes?
