As per the suggestion to post this as a feature request here
If the desktop application has Start automatically on login and Unlock with Windows Hello with Ask for Windows Hello on launch selected, it will automatically prompt you with an unlock window when you log in. However, it will not automatically minimise.
If you enable Start to tray icon it will start minimised to the tray, but then will not prompt you to unlock it when logging in.
Ideally, I would like to see either a new option or behaviour that would automatically prompt you to unlock the database when logging in to your pc, and then after unlocking automatically minimise to tray.
I personally think the best way to implement this would be to change the Start to tray icon functionality, so if Ask for Windows Hello on launch and it are selected, after unlocking it automatically minimises to tray.
