How To Create Chords from Single Notes Cubase 10

Hi Everyone,Quick question:I have a song I wanted to get done before weekend’s over.My question:How can I use the Chord track or Chord Assistant in Cubase 10 to create Chords from single notes.I watched the Youtube videos but I still didn’t get it.Thanks for help

if you open the ‘chord pads’ in the lower Zone ‘ctr alt b’ to show
it shows you pads that you can mouse click on play chords…
but also blue keys on the above piano roll to represent which keys on you connected midi keyboartd will trigger the chords…
go from there…

Ok?let me give that a shot:)Thanks
