### Token

The OAuth 2.0 access token that is provided by the identity provider. Application must get this token by authenticating the application using client credential grants before the application makes an AssumeRoleWithClientGrants call.

        // Act: len==0 triggers initial token construction
        byte[] out = ctx.initSecContext(null, 0, 0);
