How I fill color and size options on SKU? Flip Flops

On the SKU registration screen, I did not find the Color / Size fields for the registration of Havaianas flip flops. As an example, the product: “Havaianas”, SKU model “Top” / Color: “Black / Size: 37/8” does not have separate fields so that it can be imported from the ERP. I will attach the Oracle platform screen where the fields are separated. How do I do this in VTEX?
