Issues with calling a public runtime script method with a button press.

Hi, I want to call a method with a simple button press. The idea is to connect the Button Signal to a simple node and call the public method inside the RunAction. Is this possible / intended to work? What is the recommended way to do this?

When I try it I get the error message that my AutoAdaptiveManager (RuntimeScript) doesn’t exist:

Node:
using ExcursionXR.SyncLib;
namespace ExcursionXR.Nodes{
public class PlacementNode : NodeBase { // fully identically to 'MyDebugNode'
...
public void RunAction() { AutoAdaptiveManager.Instance.PlaceAll();}
}

RuntimeScript:
namespace ExcursionXR.SyncLib {
public class AutoAdaptiveManager : DataComponentBase
...
private void Start() { Instance = this; }
public void PlaceAll() {}
}

Unfortunately it seems that runtime scripts doesn’t exist for nodes. Are they compiled separately?

What should I do?
