Branding API: Access denied for checkoutBrandingUpsert field

[sanjar]

Hello !

Please can you help us on Branding API? I have followed all steps and rules provided in docs. Created custom app and using unstable version of api. My customer store is on Plus and i've created draft version of new Checkout. Now i'm trying to apply some customizations and api returns this: 

"message": "Access denied for checkoutBrandingUpsert field. Required access: The app must have access to checkout branding settings and the shop must be on a Plus plan or a Development store plan.",

Thanks!

Resolved by adding write_checkout_branding_settings access scope. whichi is not documented anywhere, poor shopify docs!
