In my application, I implemented Google signout using jsapi.
I used the url https://www.googleapis.com/oauth2/v1/tokeninfo?access_token=xxxxxx to connect to Google and then https://www.googleapis.com/plus/v1/people/xxxxxx to get user data from google profile.
Now I need to signout the user from Google while clicking a button from my application. How can I implement this in JavaScript, or at least it must ask the Google login page every time the user signs in.
I have tried approval_prompt=force, but seems not to be working.
