This is a core block and thus available by default in Gutenberg WordPress editor. No download required.

The WordPress Categories Block in Gutenberg is somewhat similar to the categories widget. The categories block displays all your post categories linking to the respective category archive pages.

Categories Block Features

The block toolbar has options for alignment. By default, the categories are displayed as a list. But it has an option in the bock settings to display the categories as a dropdown. It also has options to show as hierarchy and show post counts.
