OAuth2.0 for embedded knack views

We created a SaaS platform for small and medium businesses. It is a proprietary source code. We want to offer quick customization for some customers using knack instead of custom code.
For that we will build small apps on knack and embed some views into our app. My question is about authentication. Users login to our app using Microsoft Azure B2C, which is an OAuth2.0 platform. Can I use that token to login to the views that will be embedded into our app’s pages?
