Has anyone had any luck using the function detectCircleGridPoints? I can't get it to work and I have the Computer Vision Toolbox installed.

I have a simple calibration pattern that I would like to implement in my code, but I keep getting the following error: Unrecognized function or variable 'detectCircleGridPoints'. I am simply calling this function within my script:
fileName = 'calibration.jpeg';
img = imread(fileName);
I = rgb2gray(img);
patternDims = [9,9]
detectCircleGridPoints(I,patternDims)
What am I doing wrong?
Here is the image by the way:

To be sure, try the command for a toolbox for which you know you have a licence.
If it is a private MATLAB license you are working with, you will have to contact Mathworks Support Center, I guess.
If it is a campus licence, contact the computing center.

clc; clear all; close all;
fileName = 'https://www.mathworks.com/matlabcentral/answers/uploaded_files/864390/image.jpeg';
img = imread(fileName);
I = rgb2gray(img);
I2 = imresize(I, 800/size(I,1), 'bilinear');
im = I2;
I2 = imcomplement(I2);
bw = ~im2bw(I2, 0.6);
bw = bwareaopen(bw, 10);
bw = imfill(bw, 'holes');
bw2 = ~imopen(bw, strel('disk', 3));
patternDims = [9 9];
imagePoints = detectCircleGridPoints(im2uint8(bw2),patternDims,PatternType="symmetric")
J = insertText(im,imagePoints,1:size(imagePoints,1));
J = insertMarker(J,imagePoints,'x',Color="green",Size=5);
imshow(J)
title("Detected a Circle Grid of Dimensions " + mat2str(patternDims))
