Specify to work with localstack or Cognito Local for local testing?

[lay-z]

Not so much an issue as a question, i wanted to work with a local cognito provider while running my service locally before connecting to cognito in production. I noticed I wasn't able to specify a local host url, looking closer into the code looks like its all hardcoded in the Cognito object. Is there anyway for me to specify the url or would i have to create a PR?

class Cognito(ScopedAuth):
    """
    Verify access token of AWS Cognito
    """

    user_info = None

    def __init__(
        self,
        region: str,
        userPoolId: str,
        client_id: str,
        scope_key: Optional[str] = "cognito:groups",
        auto_error: bool = True,
    ):
        url = f"https://cognito-idp.{region}.amazonaws.com/{userPoolId}/.well-known/jwks.json"
        jwks = JWKS(url=url)
        super().__init__(
            jwks,
            audience=client_id,
            issuer=f"https://cognito-idp.{region}.amazonaws.com/{userPoolId}",
            scope_key=scope_key,
            auto_error=auto_error,
            extra=CognitoExtraVerifier(
                client_id=client_id,
                issuer=f"https://cognito-idp.{region}.amazonaws.com/{userPoolId}",
                token_use={"access"},
            ),
        )
