Adding Props to Not Return Signedin Object on Load

[hassan-righthand]

Is your feature request related to a problem? Please describe.
If cookie is saved and whenever the page is loaded, it automatically signed in without clicking on the button

Describe the solution you'd like
Adding props that will help to disable this auto request to the handler on page load.

Describe alternatives you've considered
As this feature was not present, I have to manually build the logic to stop auto requests to the handler until and unless the user clicks on the button

Additional context
https://www.npmjs.com/package/react-google-login ( something like this , isSignedIn )
