How to find the deployment environment of an azure function app in code

Scenerio is that:

1. We have Azure DevOps and we can run a pipeline into one of x number of named environments

2. We make use of Azure App Configuration, and labels for the values for each environment. So for each setting, it might have a different value depending on the label

It occurs to me that if i match up the label to the same as the names of the environments, then in code, when i get the config value, if I can somehow determine what environment I've been deployed to (speaking from the code's point of view) then i can just pass this variable when getting the app config and i will have the correct config settings for my environment.

            var environment = // HERE find my deployed to environment as in pipeline (1.)          var credentials = new DefaultAzureCredential();                  configurationBuild.AddAzureAppConfiguration(options =>              {                  options.Connect(settings.GetValue<string>("ConnectionStrings:AppConfig"))                          .Select(KeyFilter.Any, LabelFilter.Null)                          .Select(KeyFilter.Any, labelFilter: environment);              });  

I was thinking that the solution would be something of the form of setting the environment in the azure-pipelines.yaml where the pipeline somehow knows the choice of environment and then reading it in code back out of the environment variable. but i dont know how to do that, or if there is a better way to do it? Thanks in advance for any help offered.
