Tuplet spanning barline for note value across the bar

I used to know how to do this and now I don’t. I need the highlighted note to appear as a plain quaver across the barline (not visible, indicated with the red arrow. What is the tuplet incantation and technique to do this?

[This is a complex part with 7 in the treble and five in the bass.]

This property perhaps?

Wouldn’t the tuplet ratio be 14:10?
