Got some problem with movement numbering in Appendix of my thesis.

Appendix page with using following syntax.

Also I got some syntax for that, but it’s not working.

#set page(
  width: 297mm,
  height: 210mm,
  margin: (
    top: 2.5cm,
    bottom: 1cm,
    left: 2cm,
    right: 2cm,
  ),
  numbering: none,
  background: context {
    place(
      top + right,
      dx: 8mm,
      dy: 105mm,
      rotate(90deg)[#counter(page).display()],
    )
  },
)

Please share with your ideas.
