Oracle queries with keyword NOCYCLE not supported in CONNECT BY NOCYCLE PRIOR

[Hal-H2Apps]

Version
sqlglot 23.2.1.dev9

Notes
The query is working without the NOCYCLE keyword.

Fully reproducible code snippet
Oracle DB

CREATE TABLE employees (
employee_id NUMBER PRIMARY KEY,
employee_name VARCHAR2(100),
manager_id NUMBER
);

-- Insertion de données de test
INSERT INTO employees (employee_id, employee_name, manager_id) VALUES (1, 'John Doe', NULL);
INSERT INTO employees (employee_id, employee_name, manager_id) VALUES (2, 'Jane Smith', 1);
INSERT INTO employees (employee_id, employee_name, manager_id) VALUES (3, 'Alice Johnson', 2);
INSERT INTO employees (employee_id, employee_name, manager_id) VALUES (4, 'Bob Brown', 1);
INSERT INTO employees (employee_id, employee_name, manager_id) VALUES (5, 'Eva Lee', 4);

Python:
import sqlglot

sqlglot.parse_one(sql="""SELECT employee_id, employee_name, manager_id
FROM test_employees
START WITH manager_id IS NULL
CONNECT BY NOCYCLE PRIOR employee_id = manager_id;""", read='oracle')
