Hi @Expiscornovus and @Dima372 ,
thank you for all your insights on this. I succeeded in posting to Yammer via your solution in an automated fashion which is GREAT✅.
However, I have one question about it related to images again and unfortunately no one has shared a screen shot of the actual outcomes so far. Is it possible to display the images as if they were really attached to the Yammer post with a proper image?
So far all I succeeded in was attaching the images only as an og object with a little icon (Images OG_Example1 and 2) but not a proper thumbnail or the actual image experience I would like to achieve.
Is that even feasible by any means?
