SharePoint Online Welcome Message

Hi everyone!

We're using SharePoint online, modern site, and would like to simply add a "Good morning, Frank" to the top right of the home page.  Where "Good morning" would change to "Good afternoon" or "Good evening" depending on the time of day (we're all in the same time zone) and where "Frank" would be the logged in users first name.

I've seen several Web parts out there on the Web but they are all for classic SharePoint pages.  Seems like this would be easy? to do on a modern SP page?

Thanks!
