  - name: is_supported
    type: function
    desc: Check if Google Services are available & ready on the device.

    returns:
      - name: is_supported
        type: boolean
        desc: Status of Google Services on the device.

    examples:
      - desc: |-
            ```lua
            if siwg then
              local is_supported = siwg.is_supported()
            end
            ```

#*****************************************************************************************************

  - name: login
    type: function
    desc: Login to SIWG using a button.

    examples:
      - desc: |-
            Log in to SIWG using a button:
            ```lua
            if siwg then
              siwg.login()
            end
            ```

#*****************************************************************************************************

  - name: silent_login
    type: function
    desc: Silent login to SIWG.

          This function is trying to retrieve the currently signed-in player’s account.

          [icon:attention] By default login methods request `GoogleSignInOptions.DEFAULT_GAMES_SIGN_IN`.
          But if you use Disk, we have to request extra scope `Drive.SCOPE_APPFOLDER`.
          Or if you use ID token, we have to request ID token with provided client_id.
          If so it causes the first time silent sign-in to fail, except for users who
          have already signed in successfully on a different device. Turn off SIWG
          features you don't want to use in `game.project`.

    examples:
      - desc: |-
            ```lua
            function init(self)
              if siwg then
                siwg.silent_login()
