Android: Get 64mp image from Xiaomi Mi 10T

I'm trying to get the largest picture from Xiaomi device. When requesting supported resolutions

CameraManager manager = (CameraManager) getContext().getSystemService(Context.CAMERA_SERVICE);
                CameraCharacteristics characteristics = manager.getCameraCharacteristics(manager.getCameraIdList()[0]);
                StreamConfigurationMap map = characteristics.get(CameraCharacteristics.SCALER_STREAM_CONFIGURATION_MAP);
                Size[] sizes = map.getOutputSizes(ImageReader.class);

the highest resolutions I get there is 4624x3472 however when using android camera app, there is 64mp mode for taking picture. When using this mode, I'm getting image with 6944x9248 How can I get such resolution in my app?
