How to show badge in centre button

hey I really liked your library,

Is there any way to show a badge in the center button? I saw in documentation that we can only do that in items.

Start with the documentation section describing badges for navigation items, then trace the center button entry point in the Java library. Confirm whether the center button supports the same badge behavior and define done as either documenting the supported usage or recording the implementation scope needed to support it.
