const cspFiatWithdrawals = new CspFiatWithdrawals({
  jwt: 'your-jwt-token',
  env: 'prod',
  theme: 'auto',
  onCompleted: ({ amountWithdrawn, assetSymbol }) => {
    console.log(`Withdrew ${amountWithdrawn} ${assetSymbol}`);
  },
  onError: ({ errorCode, reason }) => {
    console.error(errorCode, reason);
  },
  onClose: () => console.log('Closed'),
  onEvent: (event) => console.log('Event:', event),

});

const container = document.getElementById('csp-fiat-withdrawals-container');
