DEJAVU ENGINE - HOW TO ENABLE DECOYS SMB ?

At dejavu15,we had smb decoy service. But when we asigned this feature,it just said "Select Customer Files". Check source code "https://github.com/bhdresh/Dejavu/blob/master/Engine/Decoify/add-server-decoys-back.php" from line 193 to 252,i uncommented all code for the feature smb,but i still not enabled it feature ? How do i use this feature ?
