This is very very loosely the plot of The Sparrow by Mary Doria Russell. They weren’t sent to necessarily convert the aliens, but the Catholic Church were the only ones willing to bankroll a trip that would take at least 60 years and have no possible ROI.
It definitely does not go as planned and, maybe unsurprisingly to modern readers, ends with the Catholic Church being cast as a bunch of perverts in the public eye.
Different premise, similar outcome, it’s fairly close to The High Crusade by Poul Anderson. Aliens invade medieval England and get shanked, ultimately leading to the British empire spanning the galaxy.
