LGTM, I took the liberty to optimize the layout a bit for positioning the icon, also moved it from play flavor to general flavor, tested successfully too 👍

[AndyScherzinger]

Merging, for whatever reason the screenshot tests aren't failing despite me changing the position of the newly introduced icon
