Identifying GitHub Enterprise License Users via Azure DevOps API

### API Spec link

https://vsaex.dev.azure.com/{organization}/_apis/userentitlements?top=10000&api-version=4.1-preview.1

### API Spec version

7.1

### Question/Query

We are using the User Entitlements API in Azure DevOps to retrieve user license details. However, we noticed that GitHub Enterprise users are being shown with "Basic + Direct" under accountLicenseType.

https://vsaex.dev.azure.com/{organization}/_apis/userentitlements?top=10000&api-version=4.1-preview.1

Currently, there is no clear way to distinguish GitHub Enterprise license users from regular Azure DevOps users via this API.

Questions:
Is there an existing API or feature that can accurately identify GitHub Enterprise license users within Azure DevOps?

Are there any upcoming updates planned to include this capability in the API?

Any insights or guidance on this would be greatly appreciated!

Thanks!

### Environment

_No response_

Start by reviewing the Azure DevOps User Entitlements API at the provided userentitlements endpoint with API version 7.1. Determine whether the response documents a reliable distinction for GitHub Enterprise users and whether an existing API or planned update addresses it. Done means documenting a confirmed API capability or a clear limitation and guidance.
