[azuredevops/test] Neither GetBuildCodeCoverage nor GetTestRunCodeCoverage returns results

[Alancere]

code:

imports (
	"github.com/microsoft/azure-devops-go-api/azuredevops/v6"
	"github.com/microsoft/azure-devops-go-api/azuredevops/v6/test"
)

	ctx := context.Background()
	organizationUrl := "myorganizationUrl"
	personalAccessToken := "myPersonalAccessToken "
	projectName := "myProjec"
	buildId := 111111
	testRunId := 222222
        flag := 7 // 1,2,4 ???
	conn := azuredevops.NewPatConnection(organizationUrl, personalAccessToken)
	testClient, err := test.NewClient(ctx, conn)
	if err != nil {
		log.Fatal(err)
	}

	coverage, err := testClient.GetBuildCodeCoverage(ctx, test.GetBuildCodeCoverageArgs{
		Project: &projectName,
		BuildId: &buildId,
		Flags:   &flag,
	})
	if err != nil {
		log.Fatal(err)
	}
	_ = coverage


	runCodeCoverage, err := testClient.GetTestRunCodeCoverage(ctx, test.GetTestRunCodeCoverageArgs{
		Project: &projectName,
		RunId:   &testRunId,
		Flags:   &flag,
	})
	if err != nil {
		log.Fatal(err)
	}
	_ = runCodeCoverage

Neither GetBuildCodeCoverage nor GetTestRunCodeCoverage returns results.
At the same time, there is another question about the options for the value of flags.
