Choice for startup screen to avoid showing confidential notes.

Is your feature request related to a problem? Please describe.
When opening the notes app, the last edited/opened note is displayed. This can be a privacy issue. For personal/confidential notes, I have to be conscious to always open another note before closing so that the personal note does not show when I re-open the notes app in case someone is standing behind me who could see it.

Describe the solution you'd like
I'd like to have a setting where I can chose what is displayed when the notes screen is opened: 1) the last edited note 2) the last open note 3) a new note 4) a blank screen

Describe alternatives you've considered
Just show a blank screen instead of a note content.

We currently have a "welcome" page that's shown if there are no notes. We can have a setting that decides if to route to the last modified note or this welcome screen:
