How to display last order ID in OpenCart?

Question

opencart

Good afternoon. I started to learn PHP and at the same time create an online store. Tell me, please, I want to display the line "Total completed orders: %s" on the main page of the site. I can't quite figure out how to do this. I found that this code will need to be inserted into the header.twig template , all that remains is to write the code :)
Picking aside But it doesn't output anything. Help me please :(
$blablabla->session->data['last_order_id'];

Found that this code will need to be inserted into the header.twig template

The code will need to be inserted in several places.
Model - Controller - Template - Language files
First read how Opencart works from the inside. According to this

I pick aside $blablabla->session->data['last_order_id'];

you have not even looked into the documentation yet, but only looked at the solution of a similar problem from the corner of your eye.
