The animation does not start

Hi, I created a project with Unreal 4.25.3 from scratch in C++. Use as a 3D character Arissa, downloaded from Mixamo.
I also downloaded the animations: Idle, Walk, Run, Jump Start, Jump Loop, Jump End. I followed the Unreal Engine tutorial “Unreal Engine 4 3rd person tutorial” until episode 10. So far so good. But when I start with Alt + P the character only moves in Idle and when I use the WSAD keys, it moves me without animation. Same with the jump. What can I have forgotten? The state machine is correct, but I don’t understand why the walk, run and jump animations don’t start. You can help me ?

possibly. On the skeletal mesh you have to assign the animation blueprint.
