The first code should be all right, but in case the default user badge (the star) is still visible below it, you can add a background to the new icon, to "hide" the default one. It will probably not be needed to do so, but if you customize the badge for a number of user groups, it might happen.

As the chat user list has a default background (for example, in the community central it's white) and a background when hovering above it (blue in the community central), the bottom code is to add a background with the same color as the user list has when hovering, so the badge would look transparent when hovering above it and won't have the default background.
