Social medias scraping/ C#

I need to create a project in visual studio 2022, .net 6 and selenium (Console app)

The main goal for this is giving a social media from a random person
exemple: https://www.youtube.com/channel/UCfnIpwbpZUi6q7w1do4ic6w

get the last video posted (first in the line)

https://www.youtube.com/channel/UCfnIpwbpZUi6q7w1do4ic6w/videos
in this case at the present time is video:https://www.youtube.com/watch?v=9mlrreMTrYE
from this URL I need to get the video thumbnail, the video title, the video description

also needs to check if the same guy is doing any live and if so get the same details for this live, thumbnail, title, description


I need similar information for the following social media:

Youtube (last post and if it has live),
Tiktok (last post and if it has live),
Facebook (last post and if it has live, last history, last reel),
instagram (last post and if it has live, last history, last reel),
