What in the world is the Connection string for nsec.app? Where do I find it? Is it the npub? Do I create it? (I tried and no go.) There is NO explanation about where to get it. Please explain for us low-brow people. *Exasperated*
Normally you'd just enter your username to the client and it would open the connection screen of nsec.app. If client is asking for "bunker url" (or just not allowing username) then go to nsec.app, open Connect app modal, choose "Advanced" and copy "bunker url". The "connection string" is nostrconnect:// string which most apps don't yet support.
