Video Autoplay on mobile with Fullscreen Slider

I am repeating my support request here as I couldn’t get any information to what I asked at my post #102450.

I have a self-hosted muted video which I put in a fullscreen slider element (also activated autoplay attribute). It works fine on desktop. I want the video to autoplay on mobile devices and fit to fullscreen (Same as desktop). How can I activate the autoplay feature for this situation? I need some clear instructions.

I see that it is possible by adding all these attributes: “playsinline”, “loop”, “autoplay” and “mute” on the video element. I tried putting the video in text element with these attributes and it worked. Is there an easy way to add these attributes to the videos in the existing fullscreen slider?

Thanks in advance, waiting for a helpful answer
