The M3 specs use specific terminology so a "contained" icon button refers to a specific type of icon button. Contained icon buttons include filled, filled tonal, and outlined styles. In the past Angular Material may have used words like "raised", "stroked", or "flat" variants but those are all wrong. You are not allowed to simply change the color of an icon button and call it something else. You can read the specs for yourself here: https://m3.material.io/components/icon-buttons/overview
