How do I load my Antarctic imagery correctly?

Due to Mercator projection limitations, imagery of the Antarctic region could not be loaded. Based on the previous suggestion, I selected the geodetic projection when slicing the Antarctic imagery, and the Antarctic image was successfully loaded, but it was distorted, and I didn’t understand how I could load it correctly. The first image is a distorted image loaded by CesiumJS. The second image is what the impact looks like in ArcGIS, the third image is a slice infographic of the image, and the last image is the code I load the slice.
