Magento continue shopping link to last added product’s category page

I’ve seen a few similar questions here when i searched but they all pertain to magento 1.

This seems identical do what i want to do..

Redirect “Continue Shopping” Button to the Current Product Category it was added from?

I see their using the Mage class which is now the object manager but is obv. frowned upon to use in magento 2. Any help would be greatly appreciated.
