“I don’t think they have ever mentioned Moshiach directly.”
That’s no accident. The hiding of meshichism is one of the most intricate conspiracies I’ve ever witnessed. Examples you can observe:
-Check out some “talk” pages on wikipedia on Jewish-related articles. Chabad-affiliated editors work tirelessly to push the narrative that mishichism doesn’t exist or is very fringe. (As a side note, they also push for the normalization of the word “misnaged” and its derivatives, but that’s another story for another day).
-Check out what happens when a Chabadnik with smicha tries to open up his own shul (eg. see the fact that there are 2 “Chabad Houses” on Colorado Springs).
-Observe how there is no mention of it on Chabad dot org, even in the comments on any articles. Seems strange given how much people clearly like discussing this issue.
Halachically, it’s better that they hide it. But, in the personal sense, it’s kind of creepy how far it goes.
