How to setup Custom Quick Checkout in opencart 2.3?

Question

opencart

Good afternoon. I was given a site and the Custom Quick Checkout plugin is installed on it, and now I need to change one field (firstname) when placing an order, now you can enter from 1 to 32 characters there. Here's how I can do it to increase this length?
Thanks in advance.

Answer 1

And why did you decide that 32? Displays a warning? The word won't fit? Cuts off? As they say: asking a question is a 90% guarantee of an answer.
