When an order is (automatically) invoiced by the plugin, an invoice notification is not sent.
I would have expected this to be the case, because this is the only way to inform the customer that their invoice is being sent.
When looking at other payment plugins, they all seem to use the \Magento\Sales\Model\Order\Email\Sender\InvoiceSender::send for sending an invoice notification, and most of the time they also add an order status history comment that an invoice notification is sent to the customer:
