[SOLVED] How to use the Privacy Plugin for a tab

I have installed the latest privacy plugin but I do not know exactly how to set it up for the following goal:
In my community I use the 'Last visitor tab' for each registered user. I would like to set the privacy settings for this tab as follows:
Each registered user who has logged in is able to see his own 'Last visitor tab' but is not allowed ot see the 'Last visitor tab' of another user he is searching for....It sounds easy but now I am playing around for hours with all the settings in the privacy area but I don't know how to do this. Please help me.

regards

OK - I think I got it - I had to reinstall the 'Last visitors' plugin at first. Then I have done the following settings:
1) Select the 'Last visitors tab' / tab 'Integration' / tab 'CB Privacy'
2) Set 'Display' to 'Forced privacy control'
3) Set 'Default' to 'Private'

hope this helps to others
