(Suggestion)Can you add a blueprint that plays in the background when the software loses focus?

[i12cu84]

At present, my environment is UE 5.2.1, which can be used normally after packing Android, but it cannot play audio in the background of Android.
I went to the UE forum and looked it up. I tried a lot of things, but it didn't work.

For example, the following method:
1.To manipulate the file:
Defaultengin.ini and BaseEngine.ini are added
[Audio]
UnfocusedVolumeMultiplier=1.0
2.UE project setting
Level Editor -> Miscellaneous -> Sound -> Allow Background Audio (tick)
3.UE BlueprintFunctionLibrary to Cpp code
UFUNCTION(BlueprintCallable, Category = "")
static float SetSUVM()
{
FApp::SetUnfocusedVolumeMultiplier(1.0f);
return FApp::GetUnfocusedVolumeMultiplier();
}

...emmm,I might need your help?
