[Python] Queryset pagination in websocket django rest framework [closed]

I have a websocket in my django drf project and a function that should read all of Notification objects from database and return them via a serializer like bellow :

@database_sync_to_async
def get_all_notifications(self):
paginator = CustomPageNumberPagination()
notifications = Notification.objects.all().order_by('-created_at')
context = paginator.paginate_queryset(notifications, WhatQuery?)
serializer = NotificationSerializer(context=context, many=True)
return paginator.get_paginated_response(serializer.data)


I do not know how to get request in socket and I think it is not accessable in socket

paginator.paginate_queryset(queryset, request)
​

my CustomPagination is as bellow :

from rest_framework.pagination import PageNumberPagination


class CustomPageNumberPagination(PageNumberPagination):
page_size = 15
page_size_query_param = 'page_size'
max_page_size = 1000


what is the solution here?
