I haven't seen anything that suggests Alby would be useful to me. Isn't it just a browser extension?
Alby is a bitcoin lightning account. You can connect it to many apps (e.g. to the browser extension).
Have you tried connecting Alby to Amethyst? https://www.youtube.com/shorts/Cx9tqunnj20

Maybe not useful to you. Unless you are trying different nostr clients ¯\_(ツ)_/¯
