Unfortunately, "active v passive" and "converter v adapter" aren't good search keywords. Advertisements usually don't distinguish between a video converter that actively processes the gpu signal vs an adapter that simply changes the physical form of the port and processes nothing. Most USBA or USBC docking stations with multiple ports process nothing, they're simply wire pass-throughs from the laptop's USB port to the  dock's ports. Price usually distinguishes between a video signal converter vs a do-nothing adapter.

Accordingly, the links posted earlier describe the actual manufacturer, model number of the converter product that people have reported to work. So you have to either buy the product from the vendor/seller in the links or search for the actual product and model number as the keywords for other vendors/seller who ship to your region.
