In oder to promote the translation/Creation of particular Wikipedia articles in particular languages for a Translation Campaign, it will be necessary to have a direct link to the CX dashboard that can be placed on a wiki-page. Visually this can take the form of a button that says "translate this article" (or similar).
However, because the source language is unknown (there might be several viable source languages) the link must route via Wikidata (see T112769 ) and give the user the option of choosing from one of the available languages. The target language might be pre-set in the link, or assumed based on the language settings of the user, or potentially also open to choice.
Furthermore, if subsequent to the "button" being placed on the wiki page the article in question now exists, the button should either replace itself with just a straight link to the article, or change to saying "article already exists" (or similar).
