Site logo keeps going under background video no matter what z-index is set to it

Hello,

I have that site where the logo hangs out of the header. I have used that positioning in other sites in the past without any problem.
In our case, here, the first thing above the header in the homepage is an Elementor container with a YouTube video background.

My issue is that the video overlaps the part of the logo hanging out of the header, and this continues happening no matter what z-index I set the logo to.

Any help?

Thanks
