In the code below, what is the lifetime of the generated token (keycloak_token) or what is the maximum permitted number of requests by keycloak_token?

import requests



def get_keycloak(username: str, password: str) -> str:

    data = {

        "client_id": "cdse-public",

        "username": "---",

        "password": "---",

        "grant_type": "password",

        }

    try:

        r = requests.post("https://identity.dataspace.copernicus.eu/auth/realms/CDSE/protocol/openid-connect/token",

        data=data,

        )

        r.raise_for_status()

    except Exception as e:

        raise Exception(

            f"Keycloak token creation failed. Reponse from the server was: {r.json()}"

            )

    return r.json()["access_token"]



keycloak_token = get_keycloak("username", "password")
