Invoices not created for Subscriptions with custom order status

For the ease of our management, we have automatically set up Subscription renewal orders to go to a custom status of Recurring (wc-recurring-order) and I dont know if that is the reason, but I see the invoices are NOT generated for these orders.

Clients can only see the invoices for their original parent order and then no other orders.

Is this as expected because of custom status or something like that?
How can we auto generate the invoices still?

In the settings, I did not see an option to add this status to the Attach to Emails.

To note – our primary concern is for the customers in their My Account page, they see the option to View all their orders but only Invoice on the parent order.

Last question here – I see on the Recurring orders I can go in and manually click Create Invoice and it will work, since we have some custom code to set that status, is there a hook or something we can call to generate the invoice when we change the status?

Thank you all!
