Currently, delete permissions for model-driven apps cannot be assigned to those created by individuals, and can only be assigned to all model-driven apps in the environment as "grant permission to delete" or "do not grant permission to delete " only.

Since there is no deletion authority for apps created by the user, the default environment is overrun with superfluous apps, and the system administrator must handle the deletion of it. 

To reduce the burden on the administrator, we recognize that the environment creator must have the authority to delete model-driven apps created by the environment creator, so we would like the scope of authority for security roles to be changed.
