Help Needed, GameLift server SKD 3.x Unreal Engine StartbackFill method documentation is very unclear

Question

I am using Gamelift with Unreal Engine and the c++ server sdk documentation for 3.x is very ambiguous. I am trying to call the startMatchBackFill() method from the server SDK and  not able to find a proper syntax definition anywhere. Can someone please share a code snippet that clearly explains/ shows how to update the matchdata using backfill method. Thanks :)

As mentioned in the below documentation, onUpdateGameSession method will be called when you initiate match backfill requests in your game.

https://docs.aws.amazon.com/gamelift/latest/flexmatchguide/match-backfill.html#match-backfill-server-data

For the startMatchBackfill operation, we currently have example for this using the JavaScript SDK...and not using the C++ as of now in the public facing documentation.

https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/GameLift.html#startMatchBackfill-property:~:text=Calling%20the%20startMatchBackfill%20operation

You can also reach out to the AWS support team for more information on your specific usecase/requirement.

Note, the previous answer linked to the AWS SDK not the Amazon GameLift Server SDK. To ensure no confusion, this is our public documentation for the 3.x Server SDK Actions w/ Unreal Engine:
https://docs.aws.amazon.com/gamelift/latest/developerguide/integration-server-sdk-unreal-ref-actions.html#integration-server-sdk-unreal-ref-startmatchbackfill

We also have some documentation on integrating with Unreal that includes code snippets for other Server SDK APIs (same syntax): https://docs.aws.amazon.com/gamelift/latest/developerguide/integration-engines-setup-unreal.html#integration-engines-setup-unreal-code
