Change swipe direction only, without swiper direction?

[SamTyurenkov]

I'm showing a webpage horizontally even in portrait orientation. However swiper detection still occurs like its rendered portrait.
How can I let user swipe vertically, while swiper direction is horizontal, but its rotated and appears vertically?

        @media (orientation: portrait) and (max-width:1200px) {
            .wrapper {
                transform: rotate(90deg);
                transform-origin: bottom left;

                position: absolute;
                top: -100vw;
                left: 0;

                height: 100vw;
                width: 100vh;
                margin: unset;
                overflow-x: hidden;
            }
        }
