When you add something to the conversation button it turns from grey to blue and stays blue for a week but my ask is for there to be an option like in Microsoft Teams where something is bold when you haven’t read it but once you click on it and read it, it is no longer bold so you know you’ve read that post.

For maybe once you read the update it changes from blue to another color. If there are many updates and they all stay blue for a week it’s hard to know if you’ve read the update already or not.
