  Is this for images? We should use the image widget so they can choose the logos from Cloudinary.

  Also I wonder in this case if we should have defaults here? That way we don't have to keep selecting the same logos over and over again 🤔, could be worth it to define two different modules, one with the default set of customer images that we maintain and one where they can manually select all of them.

                    - { name: 'src', label: 'Image', widget: 'image', required: false }
