 Now that we have created the permission, we will use it to protect the implementation. We want to make sure only the authorized callers holding the `ADMIN_EXECUTE_PERMISSION`, can use the function.
 
-Because we have initialized the [`PluginClonable` base contract](../../../03-reference-guide/core/plugin/PluginCloneable.md), we can now use its features, i.e., the [`auth` modifier](../../../03-reference-guide/core/plugin/dao-authorizable/DaoAuthorizable.md#internal-modifier-auth) provided through the `DaoAuthorizable` base class. The `auth('ADMIN_EXECUTE_PERMISSION')` returns an error if the address calling on the function has not been granted that permission, effectively protecting from malicious use cases.
