Magento2 Marketplace 3rd Party Module Support – After the approval or auto-approval of the product, all the products added by the vendor/seller will be part of the global catalog.
So any module by 3rd party will work as a normal webshop of Magento2.
However, the vendors will not work/manage the module features from the vendor panel of the marketplace. Which means the vendor will not be able to manage those module features.
Example – If you will use any other third party auction plugin then admin will be able to add auction but not the seller / vendor, in that case, you will have to use our Magento2 Seller Auction Marketplace Add-on
