Clicking OK or Sending Enter, Program with Funky Controls

[brokenchains]

I'm trying to automate a chunk of what I do as a hobby with OBS Multiplatform, a livestreaming app. The original OBS program worked with a script in AutoHotkey, but doesn't in the newer rewrite of the app. Basically while the app is not in focus I need to double click an item in a list, just click 'OK' or hit enter or space, then send the same hotkey to OBS that goes through AutoIt. I got the double click to work just fine which was the problem with AHK, but I'm struggling to click 'OK'. 

I think the real issue is that this new multiplatform version of OBS has really funky naming for its classes & controls. They seem generic - for example the main window has the class "Qt5QWindowIcon". Anyway this is my first night looking into AutoIt but from what I've cobbled together after looking through the docs and picking up scraps, I have worked up the code below. (I know I commented the ControlSend & ControlClick, that's just to point out the two options I've tried.)

Local $inTargetProg = False

Func _num2()
   ControlClick("OBS 0.11.4 (windows)","","[CLASS:Qt5QWindowIcon; INSTANCE:4]","",2,224,35)
   WinWait("[TITLE:Properties for 'CC_Transition'")
   ;ControlSend("Properties for 'CC_Transition'","","[CLASS:Qt5QWindowIcon; INSTANCE:2]","","{enter}")
   ;ControlClick("Properties for 'CC_Transition'","","[CLASS:Qt5QWindowIcon; INSTANCE:2]","",1,28,10)
EndFunc

While 1
   If WinExists("OBS 0.11.4 (windows)") and Not $inTargetProg Then
      HotKeySet("^{NUMPAD2}","_num2")
      $inWC3 = True
   EndIf

   If Not WinExists("OBS 0.11.4 (windows)") and $inTargetProg Then
      HotKeySet("^{NUMPAD2}")
      $inWC3 = False
   EndIf

    Sleep(5)
WEnd

Below is the Window Info while I hovered exactly in the center of the button I need to click. I though just sending {enter} with the ControlSend option above would do it easily but it didn't.

Any suggestions? If I missed anything I'd be glad to provide it if I can.

Use an if statement with winactive - https://www.autoitscript.com/autoit3/docs/functions/WinActive.htm

Even if I want to control the app from the background? WinActive just looks to see if it's the window in the foreground, right?

I gave you the function reference link in my post. You can see if the window is active or not then perform an action if it's active or not. You have what you need.
