Hi @kenichiwa
This would be a nice addition to that page. If it helps you at all, There is a spot you can find this info.
if you go to device management under either the organization or the group, you can download the list as a CSV from under the table of devices and in that CSV the devices licenses will be listed.
I am hopeful that your team will put that on the roadmap since InControl has been a great fleet management tool and provides a unified view of all devices.
