Integrate Alipay with Membership 2

I am having issues activating Alipay within the Membership2 plugin, I am already linked with Stripe, Alipay is also activated within the Stripe account.
I've tried the code provided here:

But I still cannot get it work. I've contacted Stripe support and they told me that there needs to be a source object https://stripe.com/docs/sources/alipay
Dont know if you can provide any insights to me on this
