How to implement online payment in Opencart only after changing the order status?

Question

opencart

Friends, hello!
1. The customer orders the product and chooses to pay online as the payment method.
2. The manager checks the availability of goods from the supplier and changes the status of the order to "online payment"
3. The client receives an email with a link to pay for the order.
Tell me how it is possible to implement this or tell me the module that solves this problem (if it exists).
Thank you!
