How to use memory streamer replay correctly?

I am trying to implement Replay KillCam while maintaining connection with DedicateServer by referring to the above document.

Replay is implemented using a memory streamer, but the connection to the server is disconnected when playing the replay.
And I don’t know how to quit playing the replay and come back.

Currently, I have created a code to toggle the Visible of DynamicDuplicateLevel and DynamicSourceLevel when playing replays. I wonder if this is the right way.

How did you do this?

Do you post a tutorial of this?

I would also like to know. I have created a game instance with the following code which works well exposed to blueprints. The only problem is that I can’t exit the played recording. Any ideas on how to accomplish this.

DeathReplayGameInstance.h

class DEMONETDRIVERTEST_API UDeathReplayGameInstance : public UGameInstance

public:

	UDeathReplayGameInstance();

	UPROPERTY(EditDefaultsOnly, Category = "DeathReplay")
		FString RecordingName;

	UPROPERTY(EditDefaultsOnly, Category = "DeathReplay")
		FString FreindlyRecordingName;

	UFUNCTION(BlueprintCallable, Category = "DeathReplay")
		void StartRecording();

	UFUNCTION(BlueprintCallable, Category = "DeathReplay")
		void StopRecording();

	UFUNCTION(BlueprintCallable, Category = "DeathReplay")
		void StartReplay();
};

DeathReplayGameInstance.cpp

#include "DeathReplayGameInstance.h"

UDeathReplayGameInstance::UDeathReplayGameInstance()
{
	RecordingName = "MyReplay";
	FreindlyRecordingName = "My Replay";
}

void UDeathReplayGameInstance::StartRecording()
{
	TArray<FString> URLOptions;
	URLOptions.Add("ReplayStreamerOverride=InMemoryNetworkReplayStreaming");
	StartRecordingReplay(RecordingName, FreindlyRecordingName, URLOptions);
}

void UDeathReplayGameInstance::StopRecording()
{
	StopRecordingReplay();
}

void UDeathReplayGameInstance::StartReplay()
{
	TArray<FString> URLOptions;
	URLOptions.Add("ReplayStreamerOverride=InMemoryNetworkReplayStreaming");
	PlayReplay(RecordingName, nullptr, URLOptions);
}

Currently I use the exposed functions in my ThirdPersonCharacterBP, triggered by key inputs. I just need a way to transfer control back to the player. Thanks in advance.
