Piano Roll Editor not showing in the context menu. Latest Version 4.3.0

I just downloaded Musescore and I'm trying to get started with my first project (bass + guitar), and the Piano Roll Editor is not showing up in the measure context window.

I've right clicked on the measure and there is no Piano Roll editor option.

I included a picture of my current context menu options.

Do I have to download it separately? Or, do I have to enable it? I have the MuseScore Studio Version 4.3.0.

Any input is appreciated. Thank you.
