Using Zaraz w/ Bigcommerce

Hi!
I would like to use Zaraz with a Bigcommerce store. As far as I know, Bigcommerce is using Cloudflare and Zaraz can be used with any website proxied through Cloudflare (orange-clouded). I would like avoiding my traffic going through two layers of Cloudflare, so my first question is if Zaraz can be used with Bigcommerce’s account. If not, I guess I need to create my own Cloudflare account and connect it to my store. Is there anything I should be aware of or take special care of? And could I use a Pro plan in this case?

Thanks!
