Watch Series 7 Complication Icon Sizes

Is it possible to use PNGs for Watch Series 7 complication sizes?

In the human interface guidelines here https://developer.apple.com/design/human-interface-guidelines/watchos/overview/complications/ it specifies a size for the new 41mm and 45mm devices. However, in the latest Xcode (13.2.1) I can't see any way to bring up a slot for you to drop in images at these sizes; all you can get is a slot for a vector image and some of the older device sizes. Also, it seems if you don't provide a vector your existing png complication's icons appear slightly cropped when used on a 45mm device.

Is the only way to support Watch Series 7 complications to use a vector or is there some hidden way or tick box somewhere to get pngs to work?

Yeah I would love to learn that too, since some of my existing complication images look too small for the new 45mm apple watch
