To give a role the ability to display or output all of the end points under the /secrets/apps/* end point it would need to have which capability set?

The `update` capability allows an entity to modify data at a path, not to enumerate existing paths or keys.

The `read` capability allows an entity to retrieve the content of a specific secret at a given path, but not to list all secrets or sub-paths within a directory-like structure.

The `sudo` capability grants elevated privileges for specific operations, often to bypass other policy rules, but it's not the standard capability for simply listing paths.

The `list` capability in a Vault policy is specifically designed to allow an entity to enumerate (or list) the keys or sub-paths available at a given path prefix, such as `/secrets/apps/*`. Without the `list` capability, even if `read` is granted, an entity cannot discover what secrets exist within a 'directory' but must know the exact secret path.

The `list` capability is indeed the correct one for this operation.
