Yes, thank you for the tutorial, that's worked.

I just got the problem to request payment/invoice from https://htlc.me/, (due to temporary network connectivity issues). but it's ok for an on-chain deposit, which I have received in minutes.

So where I can find node address (pubkey)?,  because I try another faucet that needs pubkey (I tried pubkey in the config, that isn't worked), https://faucet.lightning.community/.

Can we set an expired payment? look like 24 hours set by default. I want to set it in 2 hours expired time.
