Google Pay has appeared as option on site?

I've been working on a friend's website today, and was editing, but no where near the shop, Woo commerce, product pages etc. Now she has the option to use Google Pay on her product pages… I definitely didn't set this up. Her website is connected to stripe, but I don't have access to her account and she hasn't altered anything on her website or stripe account. Why is this now coming up and how can I remove it? Any help greatly appreciated, because it's currently looking like I'm responsible.
