Can a merchant accept a chargeback on Coinbase?

Could you please elaborate on whether or not merchants have the capability to accept a chargeback when transacting on Coinbase? Given the nature of cryptocurrency transactions and their inherent differences from traditional financial systems, I'm curious to understand if Coinbase, as a major cryptocurrency exchange, allows merchants to facilitate chargebacks in the event of a dispute or unauthorized payment. Would such a process be handled similarly to traditional card networks, or does Coinbase offer a unique approach to resolving such issues?
