When writing technical documentation (manuals), it's always linked to a certain version of the software/app. Currently when writing tech docs in confluence, we have our confluence pages, and on top, we add from which version that feature is supported. However, it would be way more UX friendly if the end user can choose for which version of the software he or she wants the docs. For example, see the button on the top right of docs (of gitlab):

This means: we actually need a button that links to a certain version of the docs we're writing.
How can we achieve this in confluence?
Thanks.
