Please explain like I am 5. Trying to do this for Damus on my mobile iOS with 3 tabs open: zapplpay.com, my alby account in safari and nwc.getalby.com in another safari tab. Intuitively I copy my npub into the npub field on zapplpay and the pairing secret from nwc.alby.com into the nwc connecting string field on zapplpay… But that is not working.
