    // It is assumed you've already generated a CSR.
    // Also, you'll need an OTP code, valid for 1 hour, which is generated online in the Fatoora portal.  See 
    // https://zatca.gov.sa/ar/E-Invoicing/Introduction/Guidelines/Documents/E-invoicing%20Detailed%20Technical%20Guidelines.pdf

    // Manually replace this with the OTP code you interactively obtained in a browser session from the Fatoora portal.
    // The OTP code is valid for 1 hour.
    otp := "123434"

    // You should already have a CSR in a file containing something that looks like this:
