Zapplepay.com is a good way to zap when it is not available in your client.
But be aware, you need to give away your Nostr wallet connect string which is essential. This string should NOT be given away without concerns. If you want to try it out make a burner account and connect alby to your npub of choice. And then you can make paste it on zapplepay.
Not to be trashing the work of the people behind zapplepay; in fact ITS AMAZING but I’m not willing to give this info without concerns, as you should.
