Trying to get an animation montage to play

Does anyone have any advice? I am trying to get a mesh to play an animation montage. The mesh was downloaded as an .fbx asset and imported into Unreal Engine 5.7.1.

I created a simple animation montage that waves legs around; when I open the montage it plays the way I expect it to. However, I can’t get my ‘enemy’ character to play the montage on the screen. I’ve even tried executing it on 'Event BeginPlay’. The montage is not played at all and the enemy just goes through its normal behavior (chasing me around without any animation).

If you created your character from scratch, ensure that it has an animation blueprint, is using said animation blueprint, and has a default slot for montages.
