Symfony 4.4 Commands are not detected

[cs-alok-agarwal]

Trying to decrypt my DB using AES256 encryptor, but when using the command given for encryption and decryption

php bin/console doctrine:encrypt:database
It is giving command not found.

[error] Error thrown while running command "'doctrine:encrypt:database'". Message: "There are no commands defined in the "doctrine:encrypt" namespace.

I installed the package and given all the necessary configurations as required.
I'm using Symfony 4.4 and PHP 7.3.11

I don't know if I'm doing something wrong or if it's a bug. I would appreciate any help you can give me.

Thanks for your time.
