Tableau integration

Hi al

I am trying to test including a tableau dashboard on my app. I am on a free account.

I use the tableau component from retool point to a public tableau dashboard. It works perfectly. URL -> https://public.tableau.com/views/getData_Demo/getData_Demo?:embed=y&:display_count=yes

However when I replace the URL with mine, which has a different domain https://prod-apnortheast-a.online.tableau.com it doesn't show up at all, not even a login screen for password.

I come across this post from this forum; and I wonder whether I need to setup the CSP for different domain. I have a similar issue for iframe, even if I put in google.com as the iframe sources.

However, I am unable to locate such option in my retool setting and adding different domain in the CSP. Do I have to upgrade to teams or business account in order to change these? Is there any samples for my reference? I spent quite some time navigating the retool doc but can't find too much instructions.

Thanks a lot.
