Character asset walk at the same spot

Hi,

I bought Poly Character Asset (https://assetstore.unity.com/packages/3d/characters/low-poly-characters-mega-pack-132403) for an animation project. I want to make the character move while walking. However it doesn't work. Is it because it use generic type of animation? I got no problem to move humanoid character.

This is my project video:

Please help.
