HOW TO REMOVE A FOLDER FROM MY LOCKBOX TO MAKE IT VISIBLE PERMANENTLY

Hi, I installed my-lockbox and since it's in English, I didn't quite understand the procedure to hide a folder and accidentally included the entire "desktop" folder instead of just one folder on the desktop. So when I lock my lockbox, all the icons and shortcuts that were on my desktop disappear. To get them back, I have to unlock it, but how do I remove it from my lockbox so that it becomes visible to everyone again? I don’t know much English and I’m afraid of making another mistake. I haven’t found anything on the web about this.
Thank you in advance.
