Why enter full screen by left clicking on the page, why don't just use the mouseenter event, no need to click?
document.documentElement.requestFullscreen() needs a user gesture, to avoid abuse.
But:
chrome://flags/#automatic-fullscreen-content-setting

the .js would be:
function $(){document.addEventListener("mouseenter",()=>{document.documentElement.requestFullscreen()
_=new AbortController()
addEventListener("mousemove",e=>{if(e.y==0){document.exitFullscreen()
_.abort()
$()}},{signal:_.signal})},{once:true})}
$()
