MutateLabelsRequest.Operations cannot be assigned to -- It is read-only

[powell-graphika]

Describe the bug:
MutateLabelsRequest.Operations is currently set to "read-only". Users should be able to create new label with this function.

labelService: https://developers.google.com/google-ads/api/reference/rpc/v9/LabelService?hl=en
MutateLabelsRequest: https://developers.google.com/google-ads/api/reference/rpc/v9/MutateLabelsRequest

Steps to Reproduce:

        //1. Create label --> get labellID
        var test_label = new TextLabel();
        test_label.BackgroundColor = "#FFFFFF";           // In RGB: current setting white background
        test_label.Description = "test_label_Location1";  // string for labeling...currently using location Number


        List<LabelOperation> operations = new List<LabelOperation>();

        // Creates the campaign label.
        TextLabel label = new TextLabel()
        {
            BackgroundColor = "#FFFFFF",           // In RGB: current setting white background
            Description = "test_label_Location1"   // string for labeling...
        };

        Google.Ads.GoogleAds.V8.Resources.Label label2 = new Label()
        {
            TextLabel = label
        };

        operations.Add(new LabelOperation()
        {
            Create = label2
        });

         Google.Ads.GoogleAds.V8.Services.MutateLabelsRequest request = new MutateLabelsRequest()
        {
            CustomerId = customerId.ToString(),
            Operations = //read-only?
            // bug report: 
        };

Expected behavior:

MutateLabelsRequest.Operations should not just be read-only (get). It should allow user to input as well (both get and set).

Client library version and API version:
Client library version: Google.Api.Gax.Grpc 3.6.0
Google Ads API version: V8
.NET version: netcoreapp3.1
Operating system: Windows 10

You can use one of the following approaches. (I am using MutateCampaignsRequest, others are similar).

List<CampaignOperation> campaignOperations = new List<CampaignOperation>();

// Newer C# versions with collection initialization syntax.
MutateCampaignsRequest request = new MutateCampaignsRequest()
{
    CustomerId = customerId.ToString(),
    Operations = { campaignOperations }
 };
 // Older C# versions.
 request.Operations.AddRange(campaignOperations);

@AnashOommen I tried the method you provided, specifically:

• adding the brackets to the input to Operations to bypass the error I previously encountered

I got the following error:

'''
