How can we upload a product with variants?

-- HikaShop version -- : 4.4.0
-- Joomla version -- : ‎3.9.23
-- PHP version -- : 7.3.25

How can we upload a product with variants? We do the upload with the text area.

We have created the characteristic "Sauces" with different values.

Now we want to upload a product called "Sauces" with different variants (from the characteristic).

What we need in fields:
product_code, product_parent_id, product_name, product_alias, options, price_value, categories, product_vendor_id

We now have this:
product_code,product_type,product_parent_id,product_name,product_alias,options,price_value,categories,product_vendor_id
Sausjes 222,main,,Sausjes,Sausjes 222,,2.60,81,4
Harissa,variant,Sausjes 222,Harissa,,,,,4
Knoflooksaus,variant,Sausjes 222,Knoflooksaus,,,,,4

But we don't get the characteristic in the product. See attachment

Thank you for your response ... I know you can search, but I can't figure it out yet.
I have tried everything again and have "Harissa" as standard with the main product.

product_code,product_type,product_parent_id,product_name,product_alias,Sausjes,options,price_value,categories,product_vendor_id
Sausjes 222,main,,Sausjes,Sausjes 222,Harissa,,2.60,81,4
Harissa,variant,Sausjes 222,Harissa,,,,,,4
Knoflooksaus,variant,Sausjes 222,Knoflooksaus,,,,,,4

The variants have been uploaded correctly, but no default has been selected yet ??
The main product is "Sauces" and the characteristic is also called "Sauces" ... and with the main product I tell the system that "Harissa" is the default for Sauces. What am I missing here?
