Text format box above text selection

Hi!
In my personal blog, in the edit post page (using Gutemberg), the text format box (bold, cursive, links, etc) is located at the very top of the page, like this:

Both sites run the most recent WP version (5.4.1)

How can I use that dynamic toolbox in my personal site?
Thanks.
