AirDrop Help from Mac (2015) to iPhone 11 - videos won't work but pictures will

Hi! When I airdrop a small video from my Mac (2015 version, updated) to my iPhone 11, it sends it to the files. I want it to send it to the Photos or Videos folders. Why does it do that? I can't edit it on my phone in my video apps even if I open the file to the video apps. The video is blank but there is sound.
