Missing translation of some menus

I am contacting the forum to find out if there is any possibility of an update to the Brazilian Portuguese pt-br language pack. In the settings taskbar, most of it is untranslated. Even some menus, such as those on the desktop, have a translation item. I know that a lot of work goes into making a system and that there is a lot of work involved. I contacted you because I have been using version 12 for many years and I have been waiting a long time for it, so I decided to contact you through the forum.

Welcome to the Forum!

You can find here some Links to help with the Translations. But in Your Case it sounds for me more like a Gnome Translation Thing. So, it would be adressed to the Desktop.

You could try to go to Settings>Region & Language and there click on:

A Window will open where automatically will be search forinstallable additional Language Packages. Maybe there are some offered for You Language.
