Hi I just saw a CLN app tutorial for Umbrel on youtube, and I saw the person there swapping out (sending lightning funds out) and receiving liquid BTC in exchange. Since liquid is fairly fast and cheap, I thought that would be a nice way to push liquidity out and open new channels with it. So the process I did not find there is how to buy an inbound channel by sending liquid BTC (instead of on chain BTC). Is that possible?
