How migrate products from Magento database 1.9 to 2.3.2?

I migrate data from Magento 1.9 to Magento 2.3.2, after that customer adds new products to 1.9, so I’m in trouble. I have a database with new products that were added at Magento 1.9, but I don’t know how to migrate them safely and what tables I should migrate. As I know products records consist of “product entity” tables, but they connected to other tables. Here a screenshot of the database, and “catalog_product_entity” have a 17 products here. 1.9 site version is dead so I cant use admin tools for export, the only database available.
