Question / Help Having a hard time recording Twitch streams

[illibb]

I've spent a lot of time researching this but still haven't found a solution. Super simple objective...I just want to record a twitch stream screen directly. I have synced my obs account with twitch but unsure how to actually utilize that function. I try to do a browser capture but i have no control of that screen once its brought up. What is the best way to just enter a stream url and record directly from that stream source in same quality and full screen format? I've just been doing display captures manually but i'm sure there is a better way.
