Need to scrape dynamic tables from tableau/esri/powerBI dashboards

I am a researcher trying to scrape data from javascript-based data dashboards built in Tableau or Power BI. In particular, I'm looking for a way to grab data from the dynamic tables that are part of these dashboards.

Some examples:

  1. COVID-19 South Dakota Case Updates, when you click on Vaccines in the tabs, there is a county-level table that shows up of vaccine doses by county.

  2. https://montana.maps.arcgis.com/apps/MapSeries/index.html?appid=7c34f3412536439491adcc2103421d4b, has a table in the lower left side of the dashboard for vaccinations by county.

  3. Vaccines - Coronavirus COVID-19 Response, has a Tableau dashboard in the middle of the page which has a table of "Doses Administered by County of Residence".

Any tips on how to grab such data would be hugely helpful in our work to combine county-level vaccination data for COVID.

Thanks in advance!
