How can I integrate Leap Motion with UE4.25 on Mac OS?

Dear all,
I’m a junior from Taiwan. I’m working my final project now. And I would like to use Unreal Engine 4.25 and Visual Studio that compiles plugin of Leap Motion to develop the project.
Resignedly, my development environment only allows Mac OS for me to integrate them. Picture1 is the release from your website I found. But I didn’t see the same interface on my laptop. Picture2 is the final step I discovered but it seems like working for Unity.
After scratched my head for a lone time. I wrote this to you and hope to get a reply from you. Thank you very much.

Sincerely,
