vmvd on Nostr: I still haven't figured it all out yet. The bitcoin lightning address in my nostr ...

I still haven't figured it all out yet. The bitcoin lightning address in my nostr profile defines where I receive zaps, correct? The connected wallet just is responsible for where sats are sent, or am I already mixing things up here? Then what is going to happen if I use two different nostr apps using the same npub. It seems like the bitcoin lightning address is synchronized, but the wallet can be different. And although I have received the sats I have zapped to myself in the Zeus app connected via @Alby integration, I don't see the zaps in Damus / Primal. Is there any reference guide showing the dependencies?
