I noted this one before but it had issues…

That link to Orbolt beta seemed suspicious orbolt_url.exe %1 and not an otl I expected.
The Masterclass video was a good one I've seen, thanks. (Even though the sound level is pretty low, and POPs potentially damaging speakers).
It actually never mentioned the Script Node but does help to communicate what you've said. (long and mostly GUI related)
That “Script Node” isn't really usable (I think it's buggy now in 12.5) over the better/longer route of Asset creation.
Building an asset seems like an overly complicated route and you can put code or expressions in any field, it seemed there should be a simple reliable node to execute a python code block only.
The only in 3rd party form of inline script nodes route might be good but again the one I found errors and the other is suspicious at best (I prefer not to follow the link over the longer Asset route).
