Dear Devs, is there a way to create a business nsec where - let's say a team of four - can access without sharing keys in emails or DMs? Like maybe if there was a creation of a business nsec, each user will receive their own encrypted message when they open on their device? 

Maybe an external web page where one person submits a request and adds the npubs they will allow to receive a unique nsec for this business nsec? 

Like a second nsec for the master/main sec? 

Does this make sense? Lol
