I did some research and finally found out how!

Go to shou.tv/airshou and click install
Then go to settings>general and then profile or device management click trust

Then get shou.tv on the App Store and once it's downloaded log in or create an account (mine is xXAnimeGamerXx I do some live broadcasts)
Go to YouTube or google and search for the video free airshou codes by frank something
Ask for a code and like the video
If you don't have a channel I have two codes
I might be doing a drawing of the codes so yeah
Click on airshou and record or broadcast :D!
