python - How Do I transfer data from sale order to invoice when clicking on 'Create Invoice' in Odoo 14 or Flectra 1.7?

Question

I run Flectra inside a Docker container. I have custom fields in sale.order which I want to transfer to account.invoice.

class SaleOrder(models.Model):
    _inherit = 'sale.order' 
    myField = fields.Integer(string='My Field', default=21, required = True)

    @api.multi
    def _prepare_invoice(self):
         res = super(SaleOrder, self)._prepare_invoice()
         # res.update({
         #     'myField': self.myField,
         # })
         res['myField'] = self.myField
         return res


class SaleInvoice(models.Model):
    _inherit = 'account.invoice' 
    myField = fields.Integer(string='My Field', default=21, required = True)

I tried to override _prepare_invoice and also _create_invoices in different variations, but none worked. From my understanding they should have worked, but I am new to Odoo/Flectra, so I would be happy for any help.

I use Flectra 1.7 (Community Edition) which I think corresponds to Odoo 14.
