Append note to Fantastical via call back url

Hi,

I am trying to append a note to fantastical from drafts. This would simply be a set of notes for a meeting. I want to add a link to the notes section in fantastical so I can quickly access the note. I feel like this should be possible via a call back url scheme but I am not familiar on how to do this? thanks in advance to anyone who can help!

URL scheme =

x-fantastical3://parse?sentence=Sentence&notes=Sentence
