how can you force a line break?

[pdxdjazz]

I notice there's now a newline button next to the note window, I think that's right, on the osX version anyway. It simply writes \\ as text. However, it doesn't seem to do anything, I've tried putting it at the start of the bar I want on the next line and at the end of the bar prior to that but nothing is displayed differently in the editor, nor if I save and exit. Is this functionality working yet, or am I making a mistake?
Thanks

The latest iRp update for Mac 2021.6 includes "multi-line staff text"

If you type text (abc) in the editor, I can’t give you\\anything but love - when saved, it should appear:

I can’t give you
anything but love

Baby!...so I’m told...
