Animation instead of image

Hello! I have recently bought this asset.

It has placeholders for images but i have tried as many times and ways and I can't get to replace the single image with a sprite animator. Is there a way to link my sprite with its animator instead of the single image prefab? If I drop inside the prefab the code didn't show it. So I think I need to attach directly to the prefab, but again, that didnt work either. I test in a lot of unity versions too, and nothing .

Here is the Scene with all the elements and the image is asking for.

I found the solution. It was just a camera issue. i fixed with this threat.
