I'm not getting the "Open Anyway" button option in Security Preferences when I try to start a new app I downloaded.
Please refer to Open a Mac app from an unidentified developer - Apple Support and / or Safely open apps on your Mac - Apple Support.
It is different now. If an application is not signed, you need to start it in a different way but ONLY the first time you use it (afterwards you can just double click to launch, or whatever method you prefer).
Control-click the application in the Finder and from the contextual menu choose Open. The dialog window you get will have an extra button that says “Open”.
Does Open Anyway still work for everybody using 10.15.6
