How do I change the base camera size in Harmony?

How do I change the base camera size in Harmony mid-project? The rectangular box that shows what will be shown on screen is what I’m referring to. Thank you for any reply, have a great day!

From the top menu bar select Scene then Scene Settings from the drop down menu. Adjusting Resolution is how it is done.
