Using the NWC option shown in the picture above, you can add those credentials (copy & paste, or QR code) into Damus as your zaps wallet to one-tap-zap, and use the built-in lightning@address to receive zaps. All in and out from the same wallet. 

Works amazingly well 

 There should be a some guide on how to do this

If not I should make one..🤔
