2015 MBP (Thunderbolt 2) output to Thunderbolt 3 Dock

I have a 2015 MBP (Thunderbolt 2), and I want to output to a new Thunderbolt 3 docking station. The new dock is connected to 2 monitors. Seems like what I need is a male to male Thunderbolt2 to Thunderbolt3 cable. But, from googling around, doesn't seem like such a cable exists. I see USB C to Mini DP male to male. But that's used for new laptops (USB C) to drive older displays (Mini DP). I also see that Apple provides a Thunderbolt 3 to 2 dongle. https://www.apple.com/us_smb_83039/shop/product/MMEL2AM/A/thunderbolt-3-usb-c-to-thunderbolt-2-adapter Thunderbolt 3 is male, Thunderbolt 2 is female. So I guess I could connect a Thunderbolt 2 cable from may MBP to the dongle. But even then, I'm not sure if that would work. Also, I'm not sure if it'd be driving 1 display or 2. Can anyone help? Thanks
