You can start by showing all available offers, if like to see what you require to earn 100000 sat on Lightning.
After testing several wallets, I'm sticking to a custodial LN wallet for now. That makes transactions much easier, saves on fees, and for amounts of only a few dollars' worth I don't mind the risk.
