Request: Show the signed in toast for returning users also.

First off, this is an amazing plugin, thank you!

I would prefer an option to turn off the 'silent sign in' for a returning player. In most other games with Play Games it welcomes me back whenever I start the game.

I like that reminder that I'm logged in and can compare my scores with others.

Thanks!

With further testing, I believe it may already do this. For when the user does need to be authenticated again.

Thanks.
