Why are Bezier curves unusable?

Godot Version

Godot 4.7 Stable, Mobile

Why can’t I use the Bezier curve feature in AnimationPlayer/Track: Skeleton3D: Rotation?Why can’t I use the Bezier curve feature in Animation Panel?

Track: Skeleton3D: Rotation

You should inform the addon developer about it. You can also search if there are similar addons and try them out.
