📢 Communication of rejections
The user is informed if a document is deemed unusable during the process.
If the submitted document does not match the expected one, or if its quality is insufficient, the user is prompted to upload it again or recapture it.
Additionally, several checks may be performed throughout the process, depending on the configured setup. For example: expired document, failed facial comparison, or non-compliance of a supporting document.
In each of these cases, the user is invited to retry the relevant step in order to minimize KO.

🌍 Forcing the language in the user interface
It is possible to force the language of the user interface by adding the `lang=xx` parameter at the very end of the URL.
For example, to force the language in French: https://id360docaposte.com/static/process_ui/index.html#/enrollment/abcd123?lang=fr
👉 The language code (`xx`) must comply with ISO standards (e.g. `fr`, `en`, `es`, etc.).
