I want to set the Language field in the ticket to one of available custom field values - (English , French, Spanish, German) when the user calls. For example if I use this js code on the frontend of my website to initialize the web widget
zE("messenger:set", "conversationFields", [{ id: '8426045896463', value: 'german'}])
it should have pre-selected the german from the dropdown when the agen views the ticket
