Return to Resolve's first settings screen see upon first opening on Mac

I want to be able to reset my initial settings prompted when you first open Davinci Resolve 20.x on my Mac. I have used the Unintsaller and deleted the files in Library/Application Support/Blackmagic Design and then resinstalled Resolve but it opens to Resolve and does not give me the original startup screen. Help - I've spent well over an hour searching on the net to no avail. no support page for the free version on backmagic's web page as far as I could tell.
