**Tell us about your request**
I would love if Lambda support loading values for environment variables from SecrtesManager like ECS does. This would prevent varaibles to be visible in the Lambda console but still make them easily usable inside my function code.

**Which service(s) is this request for?**
AWS Lambda, Secretsmanager

Aucun fichier, test ou point d’entrée n’est mentionné. Commencez par clarifier le comportement d’intégration requis entre AWS Lambda et Secrets Manager, notamment les permissions et la manière dont les valeurs doivent être exposées au code de la fonction tout en restant masquées dans la console Lambda ; le travail est considéré comme terminé lorsque ce comportement de bout en bout est spécifié et pris en charge.
