How to Watch Amazon Prime Video with Your Friends on DISCORD
Discord’s game streaming feature lets you share your gameplay with friends in a voice channel, but you can also use it to stream video from services like Amazon Prime Video.

Your friends can then join you in the voice channel and watch along with you instantly.
