How do I rotate the screen to play portrait video 1080x1920? Raspberry Pi 3 B+ (Raspberry Pi OS Lite 64bit + Anthias v0.20.3)

Hi, yes all the assets I upload, videos, webpages or images are displayed in landscape mode. I’m attaching a photo that I uploaded among the assets. As you can see on the side of the terminal, I see it in vertical mode, but when I launch the assets, the view changes even if i upload a rotate image
