How to display user information in ocStore 2.3 - first name, last name, etc.?

Question

opencart

Hello!
I need advice from a person who is developing under ocstore or had experience. Tell me how to display user data from the database - for example, login, first name, last name on any page. What exactly to write in the controller, model and template
On the example of the product, I understood what to display
But here is a big snag with the user ..

Answer 1

there are functions in the catalog/model/account/customer.php model
public function getCustomer($customer_id)
public function getCustomerByEmail($email)
public function getCustomerByCode($code)
public function getCustomerByToken($token)
so use them
