HDMI-CEC Implimentation

I'd like to impliment an action when a CECStatus event is triggered per: https://developer.roku.com/docs/references/brightscript/events/rocecstatusevent.md

To watch for this event, a message port needs to be opened. How would I you do this? 

Here's my main.brs:   Would I put it in here?


    screen   = CreateObject("roSGScreen")
    port     = CreateObject("roMessagePort")
    
    scene    = screen.CreateScene("MainScene")
    screen.setMessagePort(port)    
    screen.show()

    while(true)
        msg     = wait(0, port)
        msgType = type(msg)

        if msgType = "roSGScreenEvent"
            if msg.isScreenClosed() then return
        end if
    end while


Thanks

    Figured out the issue. Documentation is incorrect. It should be:
    CECStatus.IsActiveSource() to get the current CEC Status, not "ifCECStatus.IsActiveSource()"

        screen   = CreateObject("roSGScreen")
        port     = CreateObject("roMessagePort")
        cecstatus = CreateObject("roCECStatus")
        
        scene    = screen.CreateScene("MainScene")
        screen.setMessagePort(port) 
        cecstatus.SetMessagePort(port)
        screen.show()

        while(true)
            msg     = wait(0, port)
            msgType = type(msg)

            if msgType = "roCECStatusEvent"
                print "RECEIVED roCECStatusEvent event"
                print "MSG STATUS: "; CECStatus.IsActiveSource()
            end if

            if msgType = "roSGScreenEvent"
                if msg.isScreenClosed() then return
            end if
        end while
