Confirm Public Unlisted Apps on Non Plus Stores

We have a number of Shopify functions we use for custom discounting that cannot be done by apps; example Employee Discount codes generated within the app by Graphql mutations that discount 70% off compare_at_price if available (so we don’t sell to employees below cost). These functions are limited for now to Plus stores.

IF we go through the lengthy approval process, can we install a public but unlisted app on a basic and “Advanced” store?

I have seen conflicting information that yes, we can, and no we cannot. Can a Dev confirm either way? Thanks so much!
