How can I automate data verification tests on PowerBi Dashboards?

I'm part of a small project where we have a Data Warehouse and produce PowerBi dashboards which show different kinds of data stored in the warehouse.

For example we could have a dashboard visual that shows the type and cost of each claim (e.g. A Theft claim for £1000) In table form.

My question is, are there anyway ways of creating automation test scripts so that we can check the data sums displayed on the powerBi dashboards are correct?

I could potentially create a test script that compared the data in the base query of the dashboard - but that would be before the DAX calculations were made which then the outputs are shown on the powerBi visuals. Is selenium a possibility?
