Are mirrored facets possible in Observable Plot?

I would like to plot two cells (right, left) where the the x axis of the left one shows the cells in descending order from left to right and the right cell has them in ascending order. I’ve use facet and reverse:true, but can’t seem to get this to work. TIA if you have any suggestions.

Hello, is this the kind of image you had in mind?

Hi Philippe,
Many thanks for this. Just what I needed.
Best regards,
Gabriel
