Hi @TheCreepster1 ,
Please refer to this article to embed feed into Yammer and have a try. If it is still not supported, you could submit this requirement to Yammer.
Hello, thanks for your reply, but this is the reverse of what I am asking. This article seems to refer to displaying data from Yammer in your HTML based application, what I want to do is display a Power BI report or dashboard on a Yammer page.
