Can't create payment app from partner dashboard

hi team,

I have read the instructions from https://shopify.dev/apps/payments/creating-a-payments-app/creating-a-payments-app.

I have registered a partner account and created an app.

I followed the instructions to step 6.
I choose the payments tab and it says “No extensions available”

I am sure this is a no problem, but any help with where to get started with this would be greatly appreciated

You Should ask for it from Shopify Team to give you access.
Because it’s required some conditions

For Some categories, like payments, checkout etc, you can only configure the extensions via the CLI (v3.x). I will recommend you also read information from app extensions

So ideally, you will create your app in your partner dashboard as you have done. Save it. Then go back to your terminal and run this

shopify extension create

This should load and list your current apps. Choose the app you want to configure extensions for and proceed from there

Hope this helps.
