How to pass generated data from a Auth Middleware to a Blueprint function in Flask 2?

def my_custom_validator(f):
    @wraps(f)
    def decorated_function(*args, **kwargs):
        headers = request.headers

        result_validation = some_validations(headers)
        my_data = result_validation['some_result']

        return f(*args, **kwargs, my_data=my_data)  # <-- from here I can attach it to the blueprint
    return decorated_function

demo_routes = Blueprint('demo', __name__, url_prefix='/demo')


@demo_routes.route('/', methods=['GET'])
@my_custom_validator
def foo(my_data):
    # Now I can manipulate my data from here
