Instant message on profile cb

I want to go on the profile of a member connected to him and sent an instant message. How can I integrate it into "Profile pro"?
I have Uddeim but is not an instant message but a private message !
Thank you for your help.

Sorry for my english i'm french !

I'm not familiar with "profile pro". How about checking out the Joomla Extention Directory: extensions.joomla.org/extensions/communication/instant-messaging and there is even a listing of CB compatible communication plugins: extensions.joomla.org/extensions/extension-specific/community-builder-extensions/community-builder-communication

I saw, but the only module that seems to me well, it freichatpure but I can not integrate it into the profile.
I was the person in line with cb, and people online with whom I can chat.
I would get to go on someone's profile and have a tab to chat live without private messaging!
Thank you for your help.
