Integrate Payment Gateway into Woocommerce

Hello
I need to build an integration for Simplify commerce gateway offered by comm bank Australia with a woo-commerce store.

the offered plugin is not satisfactory because:

- it offers modal payment ( a popup form to fill the card details) while i prefer an embed form.

- it directs to /order-pay page which is one additional step i wish to get rid of
- the hosted payment solution doesn't support wallets (apple pay and google pay) while the direct API solution does.
