Add target="_blank" in menu items (main navigation)

Question

I use Drupal 8.9.3 with custom theme. I need to do a menu item on the main navigation who go on an external link.

I would like to add target="_blank" on this link, but I don't see where I can put that attribute from the user interface.

Do I need a module? I would like to avoid a PHP function.

I tried https://www.drupal.org/project/menus_attribute/releases/8.x-1.2. I added my attr but nothing appears in my code.

Answer 1

The module for this is menu_link_attributes.
