RSS Feed + Yammer

Hi all,

I have a question regarding RSS FEED & Yammer.

Question is:

how to share an RSS feed in Yammer?

We have audio mp3 that we would like to share. MS Stream seems to only work for video.
Is Yammer product connected to Microsoft 365?

There are RSS feed apps in Microsoft 365 that will allow this, but my understanding is that we would find these under Group Actions.

I’d like to post an RSS feed from a Document Library for sharing webinars more easily, so I am searching for best solution there is.
Thanks,
Dino
