changeVariant(targetProductId, selectedVariantId)

If you are using a customized variation selection approach not supported by the SDK, or if you wish to change the variant in certain situations, you can achieve this by calling the changeVariant method. This method accepts two numerical parameters:

targetProductId: represents the ID of the product for which the variant needs to be changed.

selectedVariantId: corresponds to the ID of the variant that you want to select for the specified product
