Apple TB3 adapter

I'm considering hooking up an eGPU to my MacBook Air 2017. Of course, it has a Thunderbolt 2 port instead of a Thunderbolt 3 connector. I've been told that this adapter is the solution:

https://www.amazon.com/gp/product/B01MQ26QIY?&tag=egpu2017-20

The problem is that adapter seems to have the wrong connectors, as well as being TB3->TB2 instead of TB2->TB3. Additionally it has a female TB2 port instead of the male TB2 connector I'd need to plug into my Macbook. Even if it is "bi-directional" I'd need some kind of gender bender for the adapter, and I'm not sure such a thing exists.

Am I missing something here?

After a bit of research it seems like the solution might be to connect the adapter to the TB3 enclosure instead of plugging it directly into the Macbook. Can someone confirm this? That just seems backwards...

This is correct.

The Thunderbolt 3 end would connect to the eGPU and Thunderbolt 2 to the laptop. Use a Thunderbolt 2 M/M cable to connect the laptop to the adapter.

I've done this with a 2015 Macbook Pro and can confirm that it works.

Confirmed. This is correct. I've done it with a 2011 MBP with a TB1 port!

Confirmed. My tip would be to use a 1m TB2 Cable. I use this TB2 cable from Startech and it's highest quality. It even feels good touching it ;p, It never lets you down, connects my TB3 13-inch Macbook Pro 2015  with a Sonnect Breakways Puck 570 in the most relialbe way you can imagine.
