How to visualize data desktop projects after PWA retirement?

This questions is a follow-up to the discussion "Data access after Project Online (PWA) retirement".

From the "Data access after Project Online (PWA) retirement" discussion it is clear that data will not be moved somewhere else.

We are mainly using the PWA site to enable that the data from the desktop projects can be visualized in Power BI, so that we can create project and portfolio dashboards that summarize information from both desktop projects and planner projects.

Any thoughts on how this could be achieved in the future?
