For now it’s designed for in-editor only, but I’ll investigate this and maybe add runtime generation support with some future update, if nothing serious stops me. Technically it should be possible to generate it at runtime after altering some blueprints, but it might be tricky, e.g. generated asset is a Procedural Mesh Component (that you can convert to Static Mesh) that sits on (0,0,0) location by design. This also could be solved with some modifications, but there are many other possible roadblocks for this - e.g. how to control the generation parameters, how to drag the nodes around workspace at runtime, etc.
