Thanks for reaching out to me but I am looking for payment app permissions, not for subscriptions. So can you please let me know what I can do for the same if you have any idea?
My apologies - I misunderstood the scope of the issue. For payment gateway permissions, you need to apply for access and be approved. Currently, we are planning to re-open the application process this quarter. You can read more about the process here: https://shopify.dev/apps/payments/getting-started#overview
But we are existing gateway partners and approved by Shopify for payment app as well. I have created my new app and have added payment app in Extension section. So let me know what I can do further.
If you’re already approved I don’t know what would be causing the permissions error to come up. You can contact support via your Partners account using the “[Beta] Report an issue” feature to allow us to take a more in depth look at this. Please provide links and as much specific information as possible, including your account and the app that’s experiencing the issue.
