Can't add my axe fx mark 2 on my studio connection

Hi I wanna record via usb port with my axe fx on my cubase 12 artist DAW.when I go in my studio connection setup menu I see my asio audio interface but if I wanna switch to my axe fx he is not even in the menu to switch it. I checked in my vst plugins and my axe fx is there and checked.Thanks for reading and maybe help me out.
