If i understand you correctly,
you can click on the raspberry Icon in the upper left of your screen.
a menu should drop down, move your mouse cursor down to "Preferances".
a screen should open to the right of your mouse cursor and you need to
re-position the cursor into this secondary menu.
in this secondary menu, move your cursor down until "Recommended Software"
is highlighted and mouse click on this option.
you will have to wait while the system loads the software 'packages'.
Once that process has completed, you will see a list of the recommended software
the system has located. "All Programs" should be highlighted or you can select a
sub-category by clicking on one.
As an example, click on the sub-catagory "Office". You can then select "LibreOffice" which has a suite of products similar to Microsoft's Office - by clicking in the checkbox, then clicking the "OK" button.
It is a very good addition to have on your RaspberryPi.
