Settings for Mirror Acrylic with magnetic Adhesive on back

Hello,
I have a project for making a menu for our cafe. We are using a magnetic board and magnetic letters for most of the board. I want to add mirro acrylic to the board so I’ve bought some magnetic sheets. They are 20mils thick. The mirror Acrylic is standard 1/8" thick. I usually cut the mirror acrylic with the non-mirror side facing upwards and use proofrgrade black acrylic cut settings and it works good. What settings would you recommend if I wanted to stick the magnetic backing to the non-mirror side of acrylic so that I could stick it to the board. Thanks in advance.
