Business Premium Copilot Pro - Graph Powered or no?

From Tom Warren's article - https://www.theverge.com/2024/1/15/24038711/microsoft-copilot-pro-office-ai-apps 

"Most of the features that have been available to businesses for the past couple of months will be available to consumers, with the big exception of being able to summon Copilot to generate a PowerPoint deck based on a Word document. Because the consumer version isn’t powered by Microsoft’s Graph technology, this functionality isn’t available just yet."

That is the one feature I have been hoping / waiting for, lol. So if I can't get it via the Copilot Pro Consumer, the one other option is Business Premium. But the question is - does Business Premium Copilot Pro use Microsoft's Graph technology?
