Universal containers (UC) is building a mobile application that will make calls to the salesforce...

The two OAuth scopes that UCshould configure in the connected app are:

Refresh token. This scope allows the mobile app to obtain a refresh token from Salesforce when it obtains an access token. A refresh token can be used to obtain a new access token when the previous one expires orbecomes invalid. This scope enables UC to provide an optimal experience for its mobile users by reducing the number of login prompts and authentication failures.

API. This scope allows the mobile app to make REST API calls to Salesforce using the access token. The REST API allows the mobile app to access or manipulate data and metadata in Salesforce using HTTP methods. This scope enables UC to build a custommobile app that can connect to Salesforce and perform various operations on Salesforce resources.
