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](https://vsaex.dev.azure.com/%7Borganization%7D/_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 with the User Entitlements API specification linked in the issue and review the accountLicenseType behavior for GitHub Enterprise users. Determine whether the API can expose a distinct license value or whether the request needs a new capability; done requires a documented, unambiguous way to identify these users or a clear statement that the API cannot do so.
