Question

I am trying to add my own option in PhotoEditorSDK 7.0

let tools [
           .tool("MY CONTROL", UIImage(named: "back", in: bundle, compatibleWith: nil)!, BrushController(configuration: configuration)),
        ]

let controller = PhotoEditViewController.init(photo: sampleImage, menuItems: mymenu , configuration: configuration)
