View updates/revisions on an epic or story?

Hi Zenhub Community, I am a newbie, trying to work out if there is a feature/way to view updates/revisions/history on an epic or story and who made these changes and when?

Pretty important stuff and I don’t seem to get an answer, so posting it here.

Any one has a guide, link, way forward would be much appreciated.

Happy Zenhubbing!
