[Dúvida] Não deletou do banco de dados

Eu baixei os códigos do projeto e estou visualizando no VS Code, executando cada célula junto com a aula, mas na célula:

query = 'DELETE FROM clientes WHERE ID_Cliente=5008804'
with engine.connect() as conn:
        conn.execute(query)

Apareceu o seguinte erro:

AttributeError                            Traceback (most recent call last)
File c:\Users\Rafael\AppData\Local\Programs\Python\Python311\Lib\site-packages\sqlalchemy\engine\base.py:1412, in Connection.execute(self, statement, parameters, execution_options)
   1411 try:
-> 1412     meth = statement._execute_on_connection
   1413 except AttributeError as err:

AttributeError: 'str' object has no attribute '_execute_on_connection'

The above exception was the direct cause of the following exception:

ObjectNotExecutableError                  Traceback (most recent call last)
