Documentation question for Plugins (Musescore 3)

I'm not sure if this question belongs here, so let me know if it would be better somewhere else.

I have been working on a plugin for Musescore 3 and have been using mostly documentation for Musescore 2, as the handbook for plugin development for Musescore 3 is a work in progress and does not have much information. My question is, is there a way of knowing if a note is tied to another note? In Musescore 2, I would use note.tieFor (or note.tieBack) and that seems to work fine for Musescore 2, but doesn't do anything for Musescore 3.

Thanks,
Caleb
