Error on Select Apple Pay as Payment Method

First off, thanks for the awesome work on trying to integrate Apple Pay w/ Stripe. I had a go with this module on a pretty basic Commerce Kickstart site and am getting a couple of issues. First off, I'm not sure if this module is fully functional but I am trying it out to see if I can get it to work.

I've got a MacBook PRO w/ Touchbar and have Apple Pay configured and have a card setup on my Wallet. I have a site setup locally w/ an https URL. I used Safari and got all the way to selecting the 'Apply Pay' payment method but upon clicking 'Continue', I'm getting a JS not enabled error and a message saying I need to setup Apple Pay on my device first. I thought I would see that Apple 'Pay' button but it seems hidden.

I'm not sure if it's because I'm testing on localhost or if I'm missing something else. I'm not using test mode. Would appreciate it, if you have any pointers. Would love to get this module completely working. I'd like to help out in anyway I can. Thanks.
