GitHub Apps gist API

I’m trying to use the Gists API to read Gist information from my GitHub App. I tried both the V3 and V4 APIs and they return the error “Resource not accessible by integration”. I am using the user’s access token to make user-to-server requests in both cases. Is it possible to access the Gists API from GitHub Apps?

I’ve confirmed I can make an anonymous request using the GitHub V3 API. But the gist “updated_at” field in the V3 API does not reflect gist comments so I can’t use the V3 API for my purposes.
