Using the Magento 2 Marketplace Custom Attribute extension, the admin can create the custom attributes from the admin back-end panel and then assign the attributes to a selected attribute set. Now, the admin can select the custom attributes which they want to provide to the sellers while the seller is adding new products.

Now, on the product creation page the seller can see the custom attributes which are enabled by the admin.

Now, on the product page under More Information tab the customers will find the additional information regarding the product.
