Working with secured server

from ravendb import DocumentStore

URLS = ["https://raven.server.url"]
DB_NAME = "SecuredDemo"
CERT_PATH = "path\\to\\cert.pem"


class User:
    def __init__(self, name: str, tag: str):
        self.name = name
        self.tag = tag


store = DocumentStore(URLS, DB_NAME)
store.certificate_pem_path = CERT_PATH
store.initialize()
user = User("Gracjan", "Admin")

with store.open_session() as session:
    session.store(user, "users/1")
    session.save_changes()

with store.open_session() as session:
