How to properly play animation based on Blackboard key value? Question

So I have an enemy, and I want that enemy to play an animation once I feed a specific speed to the blackboard value in the behavior task bp. I have set up an animation blend space + animation blueprint that work fine if I push through values manually in the animation bp itself. So that’s fine. I have also logged to console the values I feed to the blackboard key in the behavior tree task to make sure they are there. That’s also taken care of. What I can’t figure out for the life of me, is how I feed the BB key to the animation blueprint so my guy plays the correct animation according to the speed value. I tried to google it, but posts are either half ■■■■■ in terms of answers, or straight up not what I’m looking for. Appreciate your time.
