Purchase some blank T5577 cards (the same chip that is in the NExT) like these and try to clone your work badge onto one of them. If you do so and you can swipe in with the cloned card at your work, then the same thing should work with your implant.
The implant is provisioned as EM4100, so you might still need the Proxmark to change the configuration block to indicate HID. I’m not sure, I’ve never used the blue cloner
