What is the call for logout from current Dropbox account?

What is the call for logout from current Dropbox account?

I followed exactly same procedure to configure my project using SwiftyDropbox.

I have called this to logout button in my code:

DropboxClientsManager.unlinkClients() 

But when i again login with code:

import SwiftyDropbox

func myButtonInControllerPressed() {
    DropboxClientsManager.authorizeFromController(UIApplication.shared,
                                                  controller: self,
                                                  openURL: { (url: URL) -> Void in
                                                    UIApplication.shared.openURL(url)
                                                  })
}

 it just clearing Access Tokens but does not getting logout of current user? and shows me as logged in with Allow and Cancel window?

Is there somthing i have missed out ?

Thanks in Advance!!!
