I owned BTC at the time of the fork, I had it on my bitcoin core wallet and a ledger. What is the easiest way to claim my BTcP? And wallet?

I have in my blog to get a video about litecoin Core Wallet's private key works the same as the btc Core Wallet. then bring your coins to safety and insert the private key in the BTCP electrum wallet. Can you see everything in my posts. Unfortunately, I do not know about the ledger. I wish you success
