Home bar on iPhone 11

I was just wondering how I can remove the hone bar from being visible on my new phone? Iv just purchased the iPhone 11 and before that I had the 8 so I’m not familiar with all the new touch screen features.

when I took a screenshot that hone bar was visible on the bottom of my screenshot - how can I remove it so that way I don’t have to edit every screenshot I take?

thanks :)
