Thanks for the detailed response.
Let me brief the docs. I need to run "
guesstoremote p2wpkh node_id max_channel_dbid hsm_secret", where
p2wpkh I enter my non-accessible address (that is,
bc1qk82d4lc0fq8sy30804gwzx7qc8njydthcqp535), where node_id the public key of the node that closed the channel non-cooperatively, where
max_channel_dbid my max guess of opened channels (I'll say about 15, so 15), and where
hsm_secret the location of my hsm_secret. Is that correct?
Yep,
it is!

9,001 sats to both of you via keysend.

I can give you a more detailed explanation on why that's necessary once you confirm that it has worked.
So, what's about that
max_channel_dbid?
