Simple messenger privacy setting

Anyone know if it's possible to set up privacy for Simple messenger, I want that only friends could use the Simple messenger between them

Thanks

Hello simple messenger have a privacy. look in attachment!

Thank you, I never noticed that setting.
Where you set the default permissions of simple messenger in the database? I wish by default only the friends could use it. For now I have only seen that in the table  bx_simple_messenger_privacy are stored decisions regarding the privacy of simple messenger and in Table sys_privacy_actions _simple_messenger_privacy_settings I found and I set to only friends but it seems not to take this approach

Many thanks

I have found the solution, i have change one raw of code in BxsimplemessengerPrivacy

if(empty($aObject) || !is_array($aObject))
return true;

in

if(empty($aObject) || !is_array($aObject))
return false;

and then if it not found any privacy setting the chat don't start
