You can display X and then call impixelinfo to mouse around over the image and see the values at the cursor location
imshow(X, []);
impixelinfo;

i want to find the value for the image that i have added with the question, not for the magnitude

Then this will work on the actual screenshot image you added/attached with your question:
rgbImage = imread('Screenshot 2021-10-18 230205.png');
imshow(rgbImage);
impixelinfo
