readonly props ın vue3 composition api

[XanXus96]

I am trying to get the isMobile and isLive properties from the player but it doesnt seem to work.
I tried binding thr player with a ref="player" and const player = ref(null) then when i try on player.value i only have getProvider canPlay and those types of functions without any props.
I tried also to bind :isMobile="isMobile" in the Player tag but it doesn't work as well
