How to create an affiliate panel

I could not see how to create an affiliate control panel on the backend. How do we create a page similar to this: www.hikashop.com/en/account/affiliate-program.html

You can go in the joomla menu manager and create a new menu of the type hikashop->affiliate program.
That is only available in the Business edition of HikaShop.

The affiliate program options are located in the config under the tab affiliate and the banners can be configured via the menu Affiliate->Banners

How do I create a similar panel? do you have any documentation that will guide me on how to customize this for our store / affiliate program

There is no documentation on how to create the menu because it is trivial: You can just go in the joomla menu manager and create a new menu of the type hikashop->affiliate program. That's all. You will get this page when clicking on that menu like on our website.
The documentation for the affiliate options are there:
www.hikashop.com/support/documentation/5...onfig.html#affiliate
The banners documentation is available on that page:
