We don't need to be able to edit the post authors here. Only the prefix (this should behave like Core's Author block –– No need for block alignment, but need for bold/italic/etc...)

Hii @thomasguillot

There is some confusion regarding the approach to implementation. I have followed the discussion that happened on the ticket here and implemented it to mirror the byline functionality. 🙇

Can you please guide me on the intended functionality of the block?

Sorry @AKSHAT2802 , I think there was some miscommunication on this one. Let's get the avatar block and then we can talk about this one in a quick call
