To get to the Telegram bot…

1) Visit http://ln.tips/ (a custom domain/URL) via a browser; this redirects to the URL below.

2) Visit https://t.me/LightningTipBot (a Telegram URL) via a brower; this opens up Telegram for the following handle:

3) @LightningTipBot (Telegram Bot Handle); search for this handle in Telegram to join.

After joining the Telegram bot, you get a generated lightning address, like so:

@ln.tips

Then you can attach your Nostr profile to the @LightningTipBot bot by typing the command:

/nostr add

If successfully you'll get the following confirmation message:

Nostr pubkey added.

Is the next step to paste your "@ln.tips" address into Nostr LN Address field?

How is this different than just using one's WoS (Wallet of Satoshi) LN Address?
