Where is SECOND CAMERA in BEREAL app?

here is burial app and if you want to post a people second camera so uh people who are new to this app are just wondering where is the second camera here you can just switch cameras like this but how to enable and see for example if i use in back camera how to see selfie camera if i'm using a selfie how to see my back camera so that's the whole point of burial app if i'm just taking a photo second picture is added automatically and you don't see what's happening on the second camera so don't worry like uh the second picture is taken automatically and that's what it is um and then it will just be added to your burial um so that's basically that um yeah something around it um if you need to be real this is how it works
