Setup for paypal adaptive so vendor receives 90% and main vendor receives 10%

-- HikaShop version -- : 4.3.0
-- HikaMarket version -- : 3.1.1
-- Joomla version -- : 3.9.20
-- PHP version -- : 7.3.16
-- Browser(s) name and version -- : firefox 78.0.2 on macOS 10.15.5

I need some help to complete the multivendor setup in our store, particular with setting up the vendor so that PayPal adaptive pays him 90% and the main vendor 10% when the transaction is paid by the customer. The main vendor - the owner of the website is thesiriuslibrary. Our first vendor is setup in the backend, and is called Alchimie de Lumiere.

We see that we need to create a new PayPal adaptive payment method for the vendor. The question is: Does each vendor need to setup a Paypal Adaptive account, so we that the information required can be obtained? And/Or does the main vendor need to setup a Paypal Adaptive Account? Is this account different then their normal PayPal account?

What does the field Paypal Classical mean?

For the payment methods, would I have one PayPal adaptive payment method for the main vendor, and one Paypal adaptive payment method for the vendor? Should I have the normal PayPal payment method for the main vendor? Should I have a normal PayPal payment method for the vendor?

Also, we noticed than your HikaMarket documentation is not quite up to date, and is missing a description of a few fields, and is a little out of date with not including enough information about PayPal adaptive. Perhaps it came at a later date than the documentation. Is it possible that you can bring that up to date for PayPal adaptive, so we can easily complete the setup of our multivendor store. Right now, all the payment is going to the vendor, or we can set it up so that all the payment goes to the main vendor. We want the 10% fee to go to the main vendor, and 90% of the payment go to vendor.

The Vendor Payment Content field under Taxes and Fees Option is also missing documentation.

When we specify Percent Fee for the vendor, do I put there 90% (what the vendor gets) or 10% (what the main vendor gets). That wasn't clear.

Thanks so much for your help.
