I mistakenly deleted the Feed From my Case lightning Record Page. What component do I need to use to restore this?
The Standard Lightning Page Components lists and describes what each does. There's a couple that cover the area you're looking at, but it's not clear if there's a feed below that component on the screenshot.
- Chatter Feed Component - displays the feed of the record
- Chatter Publisher Component - what you have (that we can see) in your screenshot, ability to take actions on the feed (post, tasks, email, etc).
- Chatter Component - all in one combo of #1 & #2
If all else fails, you can just drag all the components in the Lightning App Builder and see that the preview looks as you documented previously.
