that’s what I did but the file picker doesn’t work(well it doesn’t upload). I realized when I add a link on the google sheet, I then go back to the app, the video plays only when it’s the video component in the items instead of the file picker. when I switch to file picker, the video stops working. Also I have question about your video sample about the private messaging. can 2 users communicate privately or the private conversation is only with the user and the admin?
