How to resolve graphene DjangoFilterConnectionField?

Question

I have below queries in my graphene API list,

class Query(UserQuery, graphene.ObjectType):
    all_users = DjangoFilterConnectionField(
        UserType, filterset_class=UserFilter)
    all_leagues = DjangoFilterConnectionField(
        LeagueType, filterset_class=LeagueFilter)

For these connections fields I need to apply @login_required style permission.

I found that I need to resolve these api endpoints in order to apply those.

@login_required
def resolve_all_users(self, info):
    #code

But I don't know what to return from the above method? There is a model called Users and ideally all records from that model needs to be returned.

But when I apply filter on first, last, before, after, I get below error,

"message": "Query.resolve_all_users() got an unexpected keyword argument 'first'"

Please advise.

Below code shows how to resolve the DjangoFilterConnectionField and it is similar to any other Django query resolve method.

    @login_required
    def resolve_all_users(self, info, **kwargs):
        user = info.context.user
        if user.is_superuser:
            return User.objects.all()
        else:
            return User.objects.filter(user_id=user.user_id)
