question

I am trying to get and set the TitleDisplayName using Azure Servers and that would require me the

 PlayFabServerInstanceAPI api = new PlayFabServerInstanceAPI(
          new PlayFabApiSettings
          {
                  TitleId = context.TitleAuthenticationContext.Id,
                  DeveloperSecretKey = Environment.GetEnvironmentVariable("PLAYFAB_DEV_SECRET_KEY", EnvironmentVariableTarget.Process)
          },
          new PlayFabAuthenticationContext
          {
              PlayFabId = context.CallerEntityProfile.Entity.Id,
              EntityToken = context.TitleAuthenticationContext.EntityToken
          }
      );

And there is no API in the PlayFabServerInstanceAPI that helps me set the TitleDisplayName of a player. Can you suggest me any for setting the TitleDisplayName currently I am using the following code to get the TitleDisplayName

  PlayFab.ServerModels.GetPlayerProfileRequest  profileRequest = new PlayFab.ServerModels.GetPlayerProfileRequest
  {
  PlayFabId = context.CallerEntityProfile.Lineage.MasterPlayerAccountId
  };
  PlayFabResult profileResult = await api.GetPlayerProfileAsync(profileRequest);

but PlayFab.ServerModels does not have one to set it, is there a possibility to use ClientAPI and the CLientModels not the ServerAPI and the Server models because with the Client API I have seen several APIs for this purpose, appreciate any kinda help with this thank you.
