How to insert nested field in footer using Word Open XML

WW 1

Hi team,

I want to insert a nested field to an existing word doc, but I don't know how to get started.
I would like to insert the expression below.

{if {page} < 2 "some text" { if {page} < 3 "another text" {if {page} < 4 "text"}}}

Regards
