To view hidden replies on Twitter, click or tap on the tweet with hidden replies. Beneath the tweet, you'll find a message indicating that there are hidden replies. Select "View Hidden Replies" to reveal them. Twitter allows users to hide replies to their tweets if they deem them irrelevant or offensive. Once revealed, hidden replies will display along with the visible ones, allowing you to see the full conversation thread. This feature helps users manage discussions and maintain the quality of conversation threads. However, note that only the original poster and those involved can view and interact with hidden replies
