Copilot API for usage

From the microsoft admin backend it is possible to download usage from copilot, so it is possible to see how many prompts users have made etc.

But i struggle to find an API that support that lookup. If have found API that show last activity date - but need an API that shows how many prompts etc has been used.
I don´t  want to see what is prompted of course - but just to show amount of prompts, so we can verify how much usage there is and make some automation in case copilot is not used, as license then can be removed
