endpoints Models google datastore NDB

Question

I have used this lib for ndb EndpointsModel in python2.7

from src.endpoints_proto_datastore.ndb import EndpointsModel
class Organization(EndpointsModel):
  Organization having account in the system '''
  company_name = ndb.StringProperty()
  address = ndb.TextProperty()  

Now google app engine is no more support 2.7 python

Now how can i use this in python3.9 with django ?
