const sessionResult = await vscode.authentication.getSession(providerid, scops);

I am currently using the getSession method for authentication in VS Code Extensions API (version 1.76). For the needs of my project, I need to determine whether this method uses MSAL (Microsoft Authentication Library) or ADAL (Azure Active Directory Authentication Library) for authentication.

I have referred to the API documentation but did not find a clear answer. I know that Microsoft has deprecated ADAL and recommends MSAL, but I am unsure if VS Code Extensions API has made this change.

Does anyone know whether the getSession method uses MSAL or ADAL for authentication? If it is MSAL, how should I test its specific features to confirm this?

Thank you.
