 **Parameters**:
 - `--identity`: STRUST identity (PSE context + PSE application). **(Mutually exclusive with the option --storage)**
 - `--storage`: Predefined STRUST identities. **(Mutually exclusive with the option --identity)**
 - `--description`: Identity Description. **(optional)**
+- `--language-iso-code`: Language of Identity Description - if not given, the language will be deduced from the current system locale. **(optional)**
 - `--overwrite`: Overwrite the existing Identity, default is `False`. **(optional)**
