I can't fix the keyframes of the animation I imported.

Hello.
I may need to edit after importing unreale animation data.
But when I want to display animation keyframes, it puts a key per frame.
I want to see keyframes in Unreal which frames I have displayed animation before.


When I bake, it leaves a keyframe on every frame as seen in the picture.
This way, I can’t edit it the way I want.
Yes, I can do some things with additive layer and edit curve. but what i’m talking about is just being able to see and edit keyframes that i have created.

thank you.
