Display 9/16 videos in post only on phones

Hi,
I want to see vertical video with proper aspect ratio 9:16 in article on phones only.

Normally I use Essential Blocks – advanced video – it works perfect , but not with your themes.
this is custom CSS for the Essential Blocks – advanced video: eb_selector {
/*position: relative;*/
aspect-ratio: 9/16 ;
}
@media (max-width: 767px) {
eb_selector {
/*display: block;*/
}
}

Can you give me any suggestion how to do it with your TAGDIW Week PRO, tested also in GOSSIP PRO theme and it is not working also. (It only shows wordpress standard 16:9 for all videos)
Thanks Peter
