When I use the function in macOS to add or insert a photo from an iOS device it starts an app that seems to be called Sidecar on my iPhone. At times I've wanted to take images from it without the flash, but I can't seem to find a way to turn it off. It isn't controlled by the same prefs as in Camera.app. And I can't find Sidecar.app anywhere in order to change prefs there. Anyone know?
