paypal later button not being displayed

I have tried the following paypal code but it is not showing paypal later button. Is there any conditional or only us geo location will it show

  // Loop over each funding source / payment method
paypal_sdk.getFundingSources().forEach(function(fundingSource) {

    // Initialize the buttons
    var button = paypal_sdk.Buttons({
        fundingSource: fundingSource
    });

    // Check if the button is eligible
    if (button.isEligible()) {

        // Render the standalone button for that funding source
        button.render('#paypal-button-container');
    }
});
