No Asus phone supports screen mirroring directly, either you have to download 3rd party apps which will connect your phone to Your tv but only if your tv is connected on the same network ( eg. Xcast ) or you should have some casting device (eg. google chrome cast ) But no Asus phone supports HDMI to type C cables.
And the app like xcast is not going to allow you to mirror your screen but it's just gonna allow you to play content On your phone to your tv.
