How do you disable all links to Sametime Meeting (Rich Client and Webchat)

The customer uses a paid plan for WebEx and only the chat function of sametime. How can we hide all links to "Sametime Meetings" as well in web chat:

as in integrated chat in Notes Client:

In Policy - set both "Allow Sametime Meetings" and "Allow meeting links feature from chat clients" to disabled.

Yes of course this is it... I'm embarassed for not checking the obvious first...

Thank you
