Where is the iTunes GIFT button?

I have been trying to send a movie to a friend as a gift from the iTunes Store. I have tried using my MacBook Air and my iPhone 8. No obvious way to do it. Online support community directs me to this page: https://support.apple.com/en-us/HT201783 which instructs me to look for the GIFT button. I have searched high and low and can find no GIFT button anywhere. Where is it hidden? Is this an outdated instruction? Then why isn't the instruction page updated or removed? Is it no longer possible to send media to friends as gifts via Apple? Should I use the Amazon Prime or Chrome to do this in the future? Please advise. Thank you.
