Help for implementing DLSS and XESS in game menu

Hi,
I need some help for implementing dlss and xess cause theyr documentation isn’t totally clear(atl east for me)
I ve build a widget for make a pause menu with settings but I don’t understand how to make the blueprint for the various quality of both dlss and xess, for xess I think I’ ve managed it but for dlss totally no clue, I didn t understood if I have to make a blueprint also for the algoritm or just the blueprint for the buttons.

Here what i ve done:

this is correct but you have to implement it also in .build.cs if you are using c++

Here the code for the full .build.cs

// Copyright Epic Games, Inc. All Rights Reserved.

using UnrealBuildTool;

public class Ambiente : ModuleRules
{
public Ambiente(ReadOnlyTargetRules Target) : base(Target)
{
PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs;

    PublicDependencyModuleNames.AddRange(new string[] {
        "Core",
        "CoreUObject",
        "Engine",
        "InputCore",
        "DLSS"  // Added DLSS module here
    });

    PrivateDependencyModuleNames.AddRange(new string[] { });

    // Uncomment if you are using Slate UI
    // PrivateDependencyModuleNames.AddRange(new string[] { "Slate", "SlateCore" });

    // Uncomment if you are using online features
    // PrivateDependencyModuleNames.Add("OnlineSubsystem");

    // To include OnlineSubsystemSteam, add it to the plugins section in your uproject file with the Enabled attribute set to true
}
