Need to revert to iOS13 Photos editor in Photos app

I installed the Camera+ 2 app on my iPhone. In iOS Photos app, I opened a photo, selected to edit it, then selected the Camera+ 2 app as the editor. Now, every time I want to edit a photo on my iPhone in the standard Photos app, I get the Camera+2 editor. Now I can't figure out how to restore the Photos app to use its own editor. How can I do this? I'm at iOS13.5.1 on this device.
