Send the Hikaserial voucher code

-- HikaShop version -- : 4.2.3
-- HikaSerial version -- : 3.1.0
-- Joomla version -- : 3.9.18
-- PHP version -- : 7.3.16

Hello, maybe someone can help me. I have the Hikaserial module and have voucher codes created automatically.This fits as far as only the problem is, if someone buys a voucher, he will be assigned to the customer, but he will not receive the code, if I open the order, the code will be in In the e-mail I place the order but the code is confirmed and I really don't know what to do next, I have no idea what I'm doing wrong.

Or does someone have an idea how I can solve it differently so that the customer receives an email with the code after confirming the payment.

I'm grateful for any help

So the confirmation runs via the plugins PayPal, Stripe and for invoices is confirmed manually because at the moment I also have the problem
