Civ VI: Conducting Holy Wars for Fun and Profit

In Civ VI, if certain apostles die in holy battle, a relic is created.

But how can there not be an Achievement Unlocked for the way I did it? I took over a different Civ's apostle, following a different religion from mine, and then I got it killed by attacking a third Civ's apostle (from yet another religion).

Well, at least I get to keep the relic and earn some tourism points.
