Gpg plugin get access token

Hello there
Now I want to get a token when Google’s login is complete. Send the token to our server for verification.
However, after the gpg plugin is logged in, you will not be able to get any other data.
Can I use gpg access token now?
“StateManager :: GetGameServices () -> FetchServerAuthCode” is to get the token?
But there is no such way in Android, the compiler will find the error

access token is not support by gpg now.

take a look at this

OK. Thanks.

In the sdkboxplay plugin, PluginSdkboxPlay :: getPlayerAccountField (“server_auth_code”) is empty. Now sdkbox all plug-ins are not supported to get google token yet

Can I use sdkbox to get google token, thanks
