Xbox One recording with my voice?

At the moment I often record small clips (Fortnite) with the standard recording method of the Xbox One (S), which I then save on my mobile phone by simply downloading the uploaded videos from my activity feed in the Xbox app.

Only there's one problem, you can't hear my voice, only the other's voice.

I would like to hear my voice too, because what we say about it sometimes is really funny.

So how do I get mine to be heard as well as the voices of my squad?

I'm grateful for any help

You can choose in the settings that the voice is recorded

Where exactly?
