Custom articulation in 2.26 and onward

Hello! I was trying to copy one of Troy Stetina's examples: it is an arrow
at the right of the note. I've looked up the manual and saw a \atRight
command; however, this command appears to only accept articulations. After
a bit of Google-searching, I've come to find two stackoverflow answers that
worked in 2.24 but not in 2.26 and 2.27. Biting the bullet, I've asked
Gemini and ChatGPT but have not received any functional/compilable answer.
My intent is to write an arrow at 45º and put it at the right of the
written note. Any help is welcome!
