How to display all comments in the order history to the user in the front?

Question

opencart

Now it turns out like this. The user placed an order, went to his account, entered the order and saw the order history there. The order history displays only those comments that were sent in the admin panel with a notification to the buyer by email. The rest are not displayed at all. More precisely, the date of the transaction is displayed but with an empty comment field.

I don't take any notes in these comments. It is used by a service that spams there detailed data about the delivery status of TK and the location of orders. This information would be useful in the buyer's office. But enabling a buyer notification by email is not practical for this. How to disable this restriction and display the entire history of a particular order in the profile? What controller to dig, and what to change?
