Currently quick Actions offers a Submenue with choices for Quick Actions
Thats not so quick.
Id suggest to either by default show some of them straight away in the bar or let the user choose how many.
similar to what outlook does. Outlook shows you i think 3 (or 6 not sure yet) if the Bar is empty enough / Window size big enough.
Specially for repetitive tasks this becomes a real superpower to one click the action.
