At first glance those projects look like they require a user to manually authorize alby to connect - does it also have a feature to send payments to lightning addresses without requiring alby extension interaction or manual interaction ?
Hi, you can use alby-tools and alby-js-sdk to send payments with Nostr Wallet Connect. You can see some example code at https://replit.com/@bumi17/nwc-demo and ZapPlanner (https://github.com/getAlby/ZapPlanner/)

With NWC, yes. You setup the app connection once and then it can send payments on your behalf
