Is it possible to provide AcceptedArns through config file?

Hello,

I'm trying to decouple accepted ARNs list from the program.cs to a config file, I have my config options defined below in appsettings.json,

"SecretsManagerConfigurationProviderOptions": {
   "acceptedSecretArns": [ "my-arn" ]
 }

Then from the code, I just call the manager like below

 try
            {
                var config = builder.Build();
                logger?.Information("reading secure settings from secrets manager");
                builder.AddSecretsManager(region: RegionEndpoint.USWest2);
                config = builder.Build();
            }
            catch (Exception ex)
            {
                logger?.Error(ex, "Unable to configure SecretsManager");
            }
            return builder;

Here, I'm not sure if the accepdSecretArns would be passed down to the library since I don't have the environment to test AWS secrets manager. Could you share your thoughts if this is correct approach?
Also, I would like to make RegionEndpoint as configurable from the appsettings option, any thoughts if I can achieve this?

Thanks

Start with the appsettings.json options and the Program.cs call to AddSecretsManager(region: RegionEndpoint.USWest2). Trace how acceptedSecretArns and RegionEndpoint are supplied to the provider, then determine the supported configuration path for both values; done means the behavior is documented or implemented and verified with AWS Secrets Manager.
