How use RequestFullScreen for safari?

Question

i'm trying to use RequestFullScreen in my webApp, this work fine with my android phone, but i can't do it for safari on Iphone...

And i have an other question pls. I want disable longtouch vibration on any phone, this doesn't work when i use this e.stopPropagation!

thanks you!

i use webkitRequestFullScreen for it like this :

const full = document.querySelector('.fullscreen') 
full.addEventListener("click", function(){
if (full.textContent==="Plein Ecran"){
full.textContent= "Quitter Plein Ecran"
if(mydocument.requestFullscreen){
mydocument.requestFullscreen();
}
else if (mydocument.msRequestFullScreen){`
mydocument.msRequestFullScreen();`
}
else if (mydocument.mozRequestFullScreen){`
mydocument.mozRequestFullScreen();`
}
else if(mydocument.webkitRequestFullScreen){`
mydocument.webkitRequestFullScreen();`
}`
 }
 else 
 {
     if(document.exitFullscreen){
         document.exitFullscreen();
     }
     else if (document.msexitFullscreen){
        document.msexitFullscreen();
     }
     else if (document.mozexitFullscreen){
        document.exitFullscreen();
     }
     else if (document.webkitexitFullscreen){
        document.webkitexitFullscreen();

     }
     full.textContent="Plein Ecran"
 }

})`

and i tried this for the vibration.

`document.getElementById('body').addEventListener("touchstart", (e)=>{     e.stopPropagation(); }, { passive: true });`
