How to prevent 1P's icon from appearing in the Dock at startup

I may have exaggerated by saying that it's a sign of disrespect but it certainly is a nuisance having to constantly (ever single day) remove the 1P icon from the dock because it takes up one of only 3 available slots for recent apps in the dock. There are very many Mac apps that start when logging in and don't display an app icon in the dock. They only show up as a small icon in the top Mac menu bar, so I don't quite understand your point or why 1P has to display an app icon in the dock. What I don't appreciate is being told that the 1Password team is working on a fix and waiting only to realise that my request wasn't taken seriously. That's not considerate. I hope that you understand my grievances this time around. Thank you.
