Touch ID not working

I am trying to test the TouchID plugin:
But it simply does not show up on my app. I am checking it on a real device, not in emulator, all the integration is done as required ( added TouchID in app module in providers, etc.etc.) I even checked some boilerplates from github, but it still does not show up on my iphone7. I have tried mixing with but the two plugins does not work together.
