Changing the destination of the "Place Order" button on WooCommerce Checkout

So i’m trying to integrate a bookly booking form into my woo-commerce checkout process so clients can schedule a time for us to perform their services. But i’m having a hell of a time finding a simple solution.

I want the checkout experience to be as follows:
1.Client selects services in the shop page, adds them to their cart, then clicks on “checkout”
2.A Bookly booking form appears where they can book a time for us to deliver their services. Once completed they click “next”.
3. The billing information page appears and the clients fill in their billing info
4. The payment page appears and the client pays for their order.
5. Thank you page
DONE

So far i’ve managed to get the “checkout” button in the cart to go to the bookly booking form by changing the “checkout” page in my woo-commerce checkout settings to the page containing the booking form, instead of the woo-commerce checkout page.

Next I changed my bookly settings to point the Final Step URL towards the checkout page for woo-commerce.

The only problem is, once the client fills out their billing information on the checkout page and clicks on “place order” instead of going to the payment page, it goes back to the bookly booking form.

I need to find a way to point that button “place order” button towards the correct page: the payment page. It’s the final step!

If you’d like to go through the checkout yourself, follow this link and add a few products to the cart, and try to check out.
