How to pass along context with AppConfigDataClient when fetching multi-variant feature flag from AWS AppConfig?

[wani-guanxi]

I am working on .NET implementation for retrieving AppConfig data using "AppConfigDataClient" and am having difficulty in understanding how to retrieve multi-variant flags. I don't see any way in the calls using the client to pass along context or any other information to AppConfig, and the returned value only consists of "default" variant but not other variants. Has anybody successfully done anything like that using AppConfigDataClient.

I am thinking of configuring client myself and test passing context in header as explained in this documentation https://docs.aws.amazon.com/appconfig/latest/userguide/appconfig-integration-retrieving-feature-flags.html, but will have to rip off my current implementation to make that possible, so wanted to know if anybody have any experience / suggestions on how to do that.
