How to set the position and window size when starting Dopus

Every time Dopus is started by double-clicking from the desktop, the window will be maximized, obscuring other window operations. I hope that every time I start the Dopus window, the window size can be automatically adjusted (I personally feel that 1344X756 is the most suitable) and the window position (I like to be in the center of the screen), how can I do this?
