How are se supposed to do a proper backup of the channels when using nostr:npub1getal6ykt05fsz5nqu4uld09nfj3y3qxmv8crys4aeut53unfvlqr80nfm Hub with Umbrel? Is the Alby account sufficient? I cannot find the 12/24 words within Alby Hub...should I just back up the words of the Umbrella Lightning node? nostr:npub1lxktpvp5cnq3wl5ctu2x88e30mc0ahh8v47qvzc5dmneqqjrzlkqpm5xlc nostr:npub1rxysxnjkhrmqd3ey73dp9n5y5yvyzcs64acc9g0k2epcpwwyya4spvhnp8 nostr:npub1qqqqqq9tkeunk6ma4zdlgt4euev7p5c64jdmp7354x0zdrns3ars20hrhr
