Slider – bg image is cropped on top

Hello,

Is there anyway to show the background image cropped on center, if the post_slider’s width is wide enough, the image is cropped on top, I would like to be cropped at center so the image could be more representative. Something like the “object-fit: cover” does;

I have tried with this I found in another post:

.wppsac-post-slider .wppsac-post-image-bg img{
height:auto !important; 
object-fit:unset !important; 
}

and this:

.wppsac-post-slider .wppsac-post-image-bg img{
height:auto !important; 
object-fit: cover !important; 
}

but it did not solve the issue.

Thank you in advanced.
