Mate 20.04 LTS package downloader

I downloaded mate 20.04 LTS 32bit for my raspberry pi 4. It installed great but i can't find the package installer to download and install stuff like game and stuff. Is there a command i can use in the terminal to download a package to download and install packages. Thanks for the help.

you can probably use the software boutique for some stuff?? otherwise sudo apt get (package name) if you know the package name and to find it in the repository you can use apt search package name or words in the package name or description
