How to use a crypto escrow service?

Could you elaborate on the steps involved in utilizing a crypto escrow service? I'm particularly interested in understanding the process from the perspective of a buyer and seller. Would it be necessary to register an account with the escrow service? How does the fund transfer occur, and what are the security measures taken to ensure the safety of the transaction? Additionally, what happens if there's a dispute between the buyer and seller? How does the escrow service resolve such issues? I'd appreciate a detailed explanation of the entire process.
