Do you have a Wallet of Satoshi? If not, download the app. It’s simple. Then click “receive” and at the top right you will see a option to click lightning address, click it. It will give you an address that looks like an email. Paste that in your profile for lightning address.

I tried it but not sure it worked. Can you send me a sat or two to test?
I have change the lightning address now, as it seems my C Lightning BTCPay Server has a channel problem again. Now put the one on my LND node. This one should work. More channels there. If not it is maybe a TOR problem, as both run behind TOR.
