Download Douyin mobile app videos in Windows PC

This project has two parts. 1... First i want a way to open Douyin app in my desktop PC. I tried using different browsers but Douyin does not show user's videos in browser. I also tried some android emulators on my PC but Douyin app stops showing videos after few minutes in emulators. So first suggest me a way where i can open douyin app inside my windows PC. 2... After opening Douyin app in my PC, i want to download my required video by just simply clicking on a download button. This download button will appear on every video of the user. and you have to code this feature for me. Note.... I don't want to go to "share" button of a video to copy that video link and then pasting that link in any other website etc. i want to speed the process. That's why i am posting this project here.
