[Question] PayPal and Google Pay subscription integration

[97fwqf5z]

I followed the tutorial from the website:
https://developer.paypal.com/docs/checkout/apm/google-pay/

I am wondering if paypal subscriptions can be made this way and how, considering that the client currently only supports the methods:
config()
confirmOrder(confirmOrderParams)
initiatePayerAction(initiatePayerActionParams)

How to pay for a subscription made on PayPal using Google Pay?
If orders can be paid, why can't subscriptions be paid?
