Provide a way to manually email an invoice to a customer

hm... Why not though I think we should have a "Resend" operation from the invoices list (similar to "Pay" and "Download") for consistency.
So I think the patch should be updated to add this for invoices instead of the order... Though having it for orders could also be valid, but I'm just voting for consistency here...

final design should be then exposed here https://www.drupal.org/node/3522060 →

Closing this as a duplicate of ✨ Provide a resend confirmation action link for invoices Active which implemented a different approach. Feel free to reopen this if you believe there is still a gap and the need is not properly addressed.

Question to experienced:
How would you describe this use case?

Answer should be added to " https://www.drupal.org/node/3522083 → > Send via mail "

This reopening is only related to the documentation side.

How would you describe this use case?

Let's say a customer didn't receive the email as expected (was sent to spam or the email service was temporarily offline, having a way to resend the invoice allows to address that.
Similarly to the "Resend receipt" operation we have for orders.

Thanks, @jsaclsick

Can you please describe the flow to resend an invoice?

There is a "Resend confirmation" action from the invoice view page, as well as an operation on the invoices list.

Cool!
thanks
