Sametime Connect plugin in Notes 8

When developing plugins in Sametime Connect standalone client, I was able to use following tool bar icon paths as specified in “Extending Sametime Redbook”.

Of those icon paths, “buddy/additions” is the path that I have used in Sametime Connect standalone environment. However, when the same plugin was installed into Lotus Notes 8.0.1 embedded Connect client, this icon was no longer being made visible.

I would like to ask if there is a documentation that lists valid tool bar icon paths for embedded Connect client in Lotus Notes 8.
