How to detect which button is pressed in AHK?

Can somone help me to do this part of this script :

if LButton is pressed{
     Send y
}
if Rbutton is pressed{
    Send n
}

This is the script :

#If WinActive("Add ahk_exe anki.exe")
^m::
WinClose Add ahk_exe anki.exe
if WinActive("Anki ahk_exe anki.exe"){
    if LButton is pressed{
         Send y
    }
    if Rbutton is pressed
        Send n
    }
#If

I’ve tried this but didn’t work :

#If WinActive("Add ahk_exe anki.exe")
^m::
WinClose Add ahk_exe anki.exe
if WinActive("Anki ahk_exe anki.exe"){
KeyWait, LButton ,D
if not ErrorLevel{
    Send y
}
Else{
        KeyWait, RButton ,D
        Send n
}
#If

Any help please, I’Il be so appreciated
