Looking for multilingual capabilities in AGOL and/or WAB... Seems like a widget or other setting ought to be available somewhere?
An option for the public to choose a language from a list of languages in a map viewer is what we are looking for.
Searched a bit and only thing that came up was esri's option to 'Switch Language' on the bottom of their AGOL documentation pages, for example:

https://www.esri.com/fr-fr/arcgis/products/arcgis-online/overview
tried Google Translator (English to Spanish) but that throws a json error:
