Pickup Point Delivery Option Generator function

Hello,

I am trying to test the new API: Generate pickup points on my Developer Preview store.

I followed the instructions from: https://shopify.dev/docs/apps/build/checkout/delivery-shipping/pickup-points/generate-pickup-points#step-1-create-the-pickup-point-delivery-option-generator-function

I launched the application, but I do not see the settings mentioned here: https://shopify.dev/docs/apps/build/checkout/delivery-shipping/pickup-points/generate-pickup-points#step-3-set-up-shipping-to-pickup-points

I am wondering what mistake I might have made. How can I test this?
