Sorry for not replying earlier, but you cannot request liquidity from us since we are not a liquidity service provider (yet). To have inbound liquidity in your SN channel, you can push sats to SN by sending sats to yourself using another lightning wallet or to an onchain address ("swap out") with a service like boltz.exchange.

There's probably a way using lncli to pay a circular route to your own node to rebalance channels but using the method above worked well enough for me so far. I usually used an invoice from my Phoenix wallet.
