You should be able to use this link to add it to your Shortcuts app. Once it’s there you can open it to see what is doing or edit anything if you want. Basically it’s just receiving the “damus.io” link from the share button, copying the note ID portion, and then appending that to a notazap.lol URL in safari. You also need the nostore NIP-07 signing extension in safari if you want the zap to show up on the note as you. Otherwise it will show as being from an anonymous pubkey.
