In My Library we have a 'Discuss' link which points to https://meta.wikimedia.org/wiki/Talk:The_Wikipedia_Library. This is a page monitored by The Wikipedia Library team, but there are also some local discussion pages which are monitored, particularly on the English and German Wikipedias. It might be helpful to link to these too.
We could add a per-language configuration so that if a user's language is, for example, German they see (de.wiki) after the 'Discuss' link which sends them to the de.wiki discussion page. We probably only want to do this in cases where a community has asked for it or we know someone from the team or an affiliate is monitoring the page.
