Do you have funds you want to use or is this just for when you do?
Electrum has an option to withdraw lightning bitcoins back to a wallet address without closing a channel which might be one way you could do this. (I think they just charged transaction fees but I'm not sure if there was anything extra I've missed).
Cause I need buy bitcoin on DEX frequently, and withdraw bitcoin to my segwit address, segwit withdraw fee is a little bit expensive,
but LN address withdraw fee is cheap, so I want withdraw by LN , and transfer to my hardware wallet by myself.
I'll try Electrum on Umbrel, after Bitcoin core data synced. Thanks a lot.
