get_hovered_item not working

[the-s0urce]

"get_hovered_item" always returns "None" for me.

import cv2
from PIL import Image
from d2r_image import processing
import numpy as np
image = Image.open(r'C:\folder\image.png')
image_data = cv2.cvtColor(np.asarray(image), cv2.COLOR_RGB2BGR)
item = processing.get_hovered_item(image_data)
print(item)
