So, in case the citation helper can't be used directly (to preserve the OP's writing style, etc.) then at least the link can be added in a tooltip — just as I've been doing it for the full citation information — and then a backlink will appear on the corresponding zbMATH review page.

It's a messy job, but someone had to do it: fixing all the links – theHigherGeometer
