Calibrating camera question

I’m trying to calibrate my camera within Lighburn. I am using the Rowdy Roman camera mount so my camera is at an angle. However, when I go through the steps, the camera view in the lens cabration wizard is only showing a straight down view, not an angled view like in the online video. Should I just go through the steps in the video and angle the image or is there something else I need to set up in Lightburn to ensure I’m calibrating to an angled view?
