Embedding Tableau: What to do if you get the Refused to display 'https://prod-useast-b.online.tableau.com/' in a frame because it set 'X-Frame-Options' to 'sameorigin'. error or it refuses to show

I was trying to embed a Tableau report in a C360 and I kept getting a weird error. I spent lots of times in forums and this is what I found:

Replace "#/site" in the URL with "t"

The other thing you need to do is add this parameter: :embed=Yes

I added it in the parameters instead of putting it in my embed URL.

I hope this saves someone a forum rabbit hole!
