What would you write there?

I wanted to apply to host a streamer on Twitch. Now I'm faced with this question and I can't think of anything to write down there. Can someone give me a tip please?

The truth.

You describe your experiences that you have already acquired, which are important to do a good job as a moderator, i.e. Your core competencies.

Exactly and best if you have a unique selling proposition. Something you can do better than everyone else (should be helpful for streamers, of course).
