Hide admin bar in WordPress frontend for admin

With Wordpress, the frontend -so if you are logged in and looking at your website from a visitor's perspective- a so-called Admin Bar is displayed. One small toolbar in the upper area with quick access to various Wordpress functions.

This admin bar can be helpful, but it can also be annoying.
There are 2 ways to hide (remove) these:

• Click on "User" >>> click on "Your profile" >>> uncheck the "Toolbar" option (Show toolbar for me on the website)
• Enter the following code snippet in the functions.php of the theme:

add_filter( 'show_admin_bar', '__return_false' );
