where can I get the app scope private key for server side verification?

Is it the same as client's secret key?

app scope private key is the private key, and here's how to get it for Ethereum:

//Assuming user is already logged in.
async getPrivateKey() {
  const privateKey = await web3auth.provider.request({
    method: ""eth_private_key""
  });
  //Do something with privateKey
}

See https://github.com/orgs/Web3Auth/discussions/322 to learn more about how you could do with other blockchains.

It is not same as the client's secret key.
