How to prevent debugging

When I start in desktop browser, Google chrome pops up with the Developer Tools opening.
I can’t find how to prevent this.
Is there a way to stop the Developer Tools window from opening?

When you’re starting your app from AppStudio, it opens the debugger since it assumes as a developer you would want that.

Why not do so?

Well, for one thing, when I program on a laptop for a tablet the screen space is dear.
I don’t need to debug just to see how the app looks and runs.
If it doesn’t run right, that’s the only time I need to use debugging.
So, can I shut if off?
