Yes, I'm using such tools.
Those can find the button I wanted to click.
But there seems to be a case where a button cannot be found via UIAutomation.

By the way, I tried to enumerate elements which supports InvokePattern.
But this line failed to create a condition.
I tried 1, true, True but all failed.

```
set cond(invoke) [object create PropertyCondition $prop(invoke) 1]

# =>System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.ArgumentException: PropertyCondition value for property 'AutomationElementIdentifiers.IsInvokePatternAvailableProperty' must be 'Boolean'.

   at System.Windows.Automation.PropertyCondition.Init(AutomationProperty property, Object val, PropertyConditionFlags flags)

   at System.Windows.Automation.PropertyCondition..ctor(AutomationProperty property, Object value)

   --- End of inner exception stack trace ---

   at System.RuntimeMethodHandle.InvokeMethod(Object target, Object[] arguments, Signature sig, Boolean constructor)

   at System.Reflection.RuntimeConstructorInfo.Invoke(BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture)

   at Eagle._Commands.Object.Execute(Interpreter interpreter, IClientData clientData, ArgumentList arguments, Result& result)

```
