Please Help A Friend

A friend of mine got scammed recently. How? Someone pretending to be from his bank called him. Since it was his bank, he trusted the caller, not realizing it was a scam. He gave away his account details from his ATM, thinking he was helping his bank. But in reality, the scammer used this information to withdraw money from his account. It turns out the scammer used Carbon, a loan app, which suggests the fraudster has an account with Carbon. Now, I'm wondering if there's a way to recover the money through Carbon since the scammer used it. Any idea on how to recover the money?
