How to signe OUT of App Store

Whenever I sign into the App Store, it takes me FOREVER to figure out how to sign out again. And it's totally not intuitive so that you see it clearly on the same page where you see your name indicating that I am signed in. It's crazy... What's wrong with Apple. (Don't get me started on that subject.) I don't have time for this. Add to this frustration, just to sign in to ask this question, it asked me to sign into this device then to another devise to get a pass code to come BACK to this devise... This sign in and sign out process is RIDICULOUS!!!

Can somebody please tell me HOW TO SIGN OUT OF THE APP STORE on my MacBook Pro? THANK YOU.
