Custom engine start button

Couldn't find anywhere on how to disassemble the start button entirely in order to replace the front cap with a custom one on a 2017+ model...Something like this instead of those cheap stick on button covers:

US $7.58 5%OFF | START Engine Button Replace Cover STOP Key Accessories Switch Decoration Universal For Mazda 3 6 CX-3 CX-4 CX-5 CX4 CX5

Anyone happen to take apart the start button and know what it's like by chance?
