What change is required so you can grant Group4 Azure RBAC read-only permissions to all Azure file shares?

To grant Azure RBAC permissions to Azure file shares, identity-based access must be enabled on the storage account. This integrates the file shares with Azure Active Directory (Azure AD), allowing you to assign Azure AD users or groups (like Group4) specific RBAC roles, such as "Storage File Data Reader" for read-only access. Recreating storage2 with a hierarchical namespace is for Azure Data Lake Storage Gen2, not directly for enabling RBAC on standard Azure file shares. Changing the account kind to StorageV2 is generally a good practice but doesn't, by itself, enable identity-based access for file shares. Creating a Shared Access Signature (SAS) provides delegated access to resources but is not an RBAC mechanism.
