Enhanced Input Actions with Axis Values In Common UI

I also encountered this problem,and I found that I can bind InputAction in customwidget.cpp

    ConfirmHandle = RegisterUIActionBinding(FBindUIActionArgs(ConfirmEnhancedInputAction, true, FSimpleDelegate::CreateUObject(this, &ThisClass::HandleConfirmAction)));

but the type of FBindUIActionArgs.OnExecuteAction is FSimpleDelegate

FBindUIActionArgs(const UInputAction* InInputAction, bool bShouldDisplayInActionBar, const FSimpleDelegate & InOnExecuteAction)
	: InputAction(InInputAction)
	, bDisplayInActionBar(bShouldDisplayInActionBar)
	, OnExecuteAction(InOnExecuteAction)
{}


FSimpleDelegate OnExecuteAction;

That means I can’t get the axis values😂
