Migrating stripe subscriptions to shopify - Error access denied

[Jamynator]

I see I didn't post the message in the right category, can someone move the topic Subscription APIs?
I take the opportunity to add a screenshot of my problem.

I also found a topic that talks about accesses that I could potentially need but impossible to find: https://community.shopify.com/c/Subscription-APIs/Revoke-payment-method-permissions-not-working/m-p/...
Access scope potentially needed:

'read_customer_payment_methods',
write_customer_payment_methods',

Unfortunately I have to migrate the stripe subscriptions to shopify quite quickly because our previous shop had problems. I need help urgently.

Hey Jamynator,

I want to apologize for not getting back to you about this in a timely manner.

If this problem is still relevant to you, can I ask that you submit this question again? (with information about your current situation)

Sincerely,
J-ROM
