How to remove lateral menu bars so that make work space wider?

Hi there! My OS is Ubuntu 20.04 I don’t need these menu bars at all but I can’t find a way to get rid of them. Please advise me how to handle with this issue.

Hello @Serjio
Please clarify what menu bars you meant. You can make a screenshot and mark them on it. Also let us know the exact product which you are using.

Hey Alexandre! I mean these gray lateral bars with icons. As an old user of Microsoft Office and Open Office I am very uncomfortable with them. I don’t need these icons and I would like to wider work space.

Hello @Serjio
Sorry, there’s no way to hide left\right menus.
