I’m trying to get account info to find out if hierarchical namespace is enabled or not. But if I use OAuth method, this function fails…

There is no official statement, or at least I did not found it, but this comment in the unit tests.

TEST_F(BlobServiceClientTest, AccountInfo_LIVEONLY_)
  {
    // This operation doesn't support OAuth-based authorization.
    auto serviceClient
        = Blobs::BlobServiceClient::CreateFromConnectionString(StandardStorageConnectionString());

    auto accountInfo = serviceClient.GetAccountInfo().Value;
    EXPECT_FALSE(accountInfo.SkuName.ToString().empty());
    EXPECT_FALSE(accountInfo.AccountKind.ToString().empty());
    EXPECT_FALSE(accountInfo.IsHierarchicalNamespaceEnabled);

    auto containerClient = serviceClient.GetBlobContainerClient(LowercaseRandomString());

    accountInfo = containerClient.GetAccountInfo().Value;
    EXPECT_FALSE(accountInfo.SkuName.ToString().empty());
    EXPECT_FALSE(accountInfo.AccountKind.ToString().empty());
    EXPECT_FALSE(accountInfo.IsHierarchicalNamespaceEnabled);

    auto blobClient = containerClient.GetBlobClient(RandomString());

    accountInfo = blobClient.GetAccountInfo().Value;
    EXPECT_FALSE(accountInfo.SkuName.ToString().empty());
    EXPECT_FALSE(accountInfo.AccountKind.ToString().empty());
    EXPECT_FALSE(accountInfo.IsHierarchicalNamespaceEnabled);
  }

So my question is, how to find out if hierarchical namespace is enabled or not using OAuth?
