In AEM as a Cloud Service environment, the repository areas /apps and /libs are considered as
immutable, meaning that they cannot be modified at runtime by any means. These areas contain
application code and configuration that are deployed via Cloud Manager and are read-only for
security and performance reasons. Any changes to these areas require a new deployment via Cloud
Manager. Reference: https://experienceleague.adobe.com/docs/experience-manager-cloudservice/implementing/deploying/overview.html?lang=en#repository-restrictions
