Private Messaging in CB Joomla Version 4

We are looking at using CB to replace Easy Profile.
One thing we want to be able to do is let members of our admin team private message our users.
We have installed the community version of CB to test.
I can see we can private message, but it appears you have to know the exact user name of the person you want to message.
Is there an 'Ajax' type facility in the professional version where you can search a list of registered users. ie Search on name 'David' to bring up all the David's or even better search on last name (ie 'Smith).

Kind regards
David Unwin

There is not an ajax lookup feature built in unless you're connected with that person and use the connections dropdown (if enabled).

Ok, Thanks...... David
