When was the "Evangelist" title first applied to the Gospel authors?

Matthew, Mark, Luke, and John are known as the ["Four Evangelists"](https://en.wikipedia.org/wiki/Four_Evangelists) because they are believed to have written the four canonical Gospels. The word "evangelist" means a messenger of good news, but is usually used by Christians to refer to those who preach the Gospel to the lost. While it's easy to understand why it is also used for the Gospels' authors, as these books are messages of the good news, it does have a different sense. While we think of evangelists as people whose primary ministry was the direct preaching of the Gospel, this was not necessarily the case with the Gospel authors. This question is a simple one: when in church history was the title "Evangelist" first applied to the Gospel authors for their role in writing the Gospel texts? If it is not known who first called them evangelists, then what is the earliest clear mention of them with this title?
