Approach for Multi-tenant SaaS app accessing customer-owned Box folders

I am building a multi-tenant SaaS platform and looking to integrate Box. Here's the use case:

  - Customers have their own existing Box accounts
  - Each customer would share one specific folder in their Box with our account
  - Our backend needs to create subfolders and upload files into those customer-shared folders automatically
  - Content should live in the customer's Box, not ours

Which authentication would you recommend? The concern of using OAuth is that when refreshing a token it invalidates an existing token which could create issues across tenants. But I am not sure if App User and Service Account are intendedly made for the case when customers are box users
