Facing an issue with Shopify Approvals

The app :

1. Saas platform which allows users to connect thier Shopify/ meta / google acc to the platform and pull insights .

2. We use read_analytics , read_orders, read_products,read_reports

The pain point and clarification required:

The shopify review process for a non embedded public app is that we have billing in our Shopify application where billing will be handled by Shopify using their billing APIs.

But we want it to be on our application.

If we are not going through that process we would have to go the custom app route which we don't want as it's for public to connect thier Shopify shop and then manage.

We use their oauth process where users can connect thier

Question:

Whats the right way to pass the review process for the api scopes properly to make it public, the billing is on our platform itself and not maintained by Shopify.
