Proxmark 3 Easy unable to read NeXT implant

Hey! I have bought a Proxmark 3 Easy and flashed it with the latest 3.7 version Iceman firmware.
When doing a “hf search” and “lf search”, I am able to find different types of test-cards without any problem.

However, when I try to read my NeXT implant, it can’t find anything on either HF or LF. I can write/read to the NFC part with my phone without any issues, so I know the chip works.

I am new to this, so I am assuming I’m doing something wrong when using Proxmark. Do you have any pointers to what I might be doing wrong?

Positioning a big one since the coils in implants are so small, there are some good positioning photos in this post which may help;
