It looks like you want to sign the Invoice using your own code.

yes, to get the Signed PropertiesHash you can use the tag as in the guide. make sure we have 36 spaces before the <xades:SignedSignatureProperties> tag and for other tags must be formatted with 4 spaces.

    byte[] hashBytes = SHA256.HashData(Encoding.UTF8.GetBytes(xmlString.Trim()));
    string hashHex = BitConverter.ToString(hashBytes).Replace("-", "").ToLower();
    return Convert.ToBase64String(Encoding.UTF8.GetBytes(hashHex));
}

For complete code you can see my Zatca.eInvoice library in my Github Repository.

hope this help…
