Supported languages
The languages Handhold agents can hold a conversation in, by agent type, and how to set the locale.
Demo agent: Danish (da), English (en), Estonian (et), French (fr), German (de), Latvian (lv), Lithuanian (lt), Spanish (es)
Inbound Q&A & Onboarding agents (all of the above, plus): Azerbaijani (az), Bulgarian (bg), Croatian (hr), Czech (cs), Dutch (nl), Georgian (ka), Greek (el), Hungarian (hu), Italian (it), Norwegian (no), Polish (pl), Portuguese (pt), Romanian (ro), Russian (ru), Slovak (sk), Swedish (sv), Ukrainian (uk)
Setting the locale
Set the locale via the iframe URL parameter &locale= or the locale option in openDemo(). You can pass either a short language code (pl) or a full regional code (pl-PL). The region is ignored, so en, en-US, and en-GB all resolve to the same language. An unsupported locale falls back to English.
