Make the character. Make the animation. Set the character to play the animation - or even just drag the animation onto the scene.
I believe you can get sequencer to start/stop it as well.
Or, since it is 2020 I suppose, you can set up a rig with ControlRig
And manually animate in unreal - with 20 years of max experience I really hope you don’t 
I doubt you’ll find specific stuff that isn’t Game based btw. And that’s because doing things for cinematics is much more lax than it is for games. When you have 100% control of everything over 1 animation you don’t need to worry about anything at all. there’s no collision, no physics. nothing that you need to dynamically adjust for. So you animate outside the engine - possibly a full sequence of events - export 1 animation, and call it a day…
