Funny, I had a similar experience with a post that I made about extracting Polkadot keys from Trust Wallet (Trust is a poop and doesn't use a standard derivation...). I had been asking around in various Telegrams and forums (and collecting scammer DMs...).
In the end, I have up and worked it out and left a post for anyone following me...
A month or so later, someone replied to one of my forum posts saying they had found a nice guide that worked for them. And they linked to my post!
