Description

Expectation

The list_users call should accept FgaObject and look like below

        response = await fga_client.list_users(
            ClientListUsersRequest(
                object=FgaObject(type="document",id="roadmap"),
                relation="viewer",
                user_filters=[
                    UserTypeFilter(type="user")
                ],
                context=dict(ViewCount=100),
            )
        )
