Help with ragdoll

I need help to implement a recovery animation after the ragdoll effect. It should be noted that I am new, and I am struggling to understand this, and my biggest drawback is that I do not speak English and I rely on the official documentation or one or another youtube video that I translate with subtitles.

My concern is the following, I am reading the following… Animation Pose Snapshot | Unreal Engine Documentation

As I understand it, the Pose Snapshot node, captures the pose where the player is left on the ground, and when I launch the stand up montage, the pose is mixed with the stand up animation. However this doesn’t work, I noticed that I have to animate the montage, but it doesn’t work for me.

I appreciate any help. I am working on a blank project, with my own character.
