Can Business Objects connect to Google Big Query BI Engine?

We’re getting Google Big Query, which I know nothing about except this article (What is BigQuery BI Engine?  |  Google Cloud 1). It says "it’s a fast, in-memory analysis service. By using BI Engine you can analyze data stored in BigQuery with sub-second query response time and with high concurrency. BI Engine integrates with familiar Google tools like [Google Data Studio]. The [BI Engine SQL interface] feature also integrates with other popular business intelligence (BI) tools, such as Looker, Tableau, Power BI.

This article says you can connect B.O. to Google BigQuery (Create an SAP BusinessObjects Universe on the CData ODBC Driver for BigQuery 1)

I’m just trying to sort out if BI Englne is a similar tool as Tableau, Looker, Power BI? Or is it more of a SQL tool for queries and such but not the primary end user tool (like PL/SQL Developer)

Anyone have any experience with Google Big Query/BI Engine (and B.O.)?

Looker was ruled out in our procurement package because it was an additional cost to Google Big Query, (https://looker.com/). Looker is now part of Google Cloud but still its own entity (like Tableau and Salesforce)
