Thanks for the update.
As we informed earlier, it is not possible to combine funnel and bubble series in a single chart. We have achieved your requirement using ellipse annotation in chart, to depict the bubbles in the funnel series. Please find the sample attachment from the below location.
Please refer the below documentation link for more information about annotations.
Please let us know, if this satisfies your requirement.
