Can not create image menu

I would like to create an image menu.
I’ve found a guide on https://www.kadencethemes.com/creating-demo-3-layout-homepage/

Adding an Image Menu
1. Go back into the home page that you created and select the Page Builder tab (on the right) and then click the Add Row tab (on the left).
2. Give the row 3 columns.
3. Click the Add Widget tab and choose the Virtue: Image Menu Item widget.
4. Upload an image and give it a title, description and link.
5. Repeat this process so that each column has a menu item.

but I have problems with the third step, because although I have activated the Image Menu Item widget this I can’t choose it, because it is not displayed.
What is wrong?
How can I solve the problem?
