Editing sent messages on The Platform is not a straightforward process, but there are alternatives to make it possible to edit or delete messages in group chats. Here's a step-by-step guide on how to edit sent messages on Telegram:

Unfortunately, The App does not allow users to alter their messages directly from the application, but there is a workaround that makes it possible to edit messages by removing them first and re-sending them as new messages.

To alter sent messages on The Platform, you'll need to delete the message first, and then re-send the edited message. Here are the instructions to do so:

1. Find the conversation that contains the message you want to alter, and go to that chat.
   
2. Click on the message you want to edit. This will bring up an menu with various options.
   
3. On this menu, select the "Remove" option. A message will appear to ask if you are sure you want to delete the message.
   
4. Click on "Remove" to verify, and the message will be removed from the conversation.
   
5. Now that the message is removed, you can edit the message with the changes you want to make. If the message you deleted was part of a bigger conversation, it's a good idea to type a new message and send it before editing the original message.
   
6. Once you have composed the altered message, type it in the text window at the bottom of the chat pane.
   
7. Send the edited message by clicking on the "Post" icon or by clicking the paper plane icon at the bottom right corner of the chat window.
   
8. The altered message will now be displayed in the chat, and it will appear as a new message.
   
   

Note: Deleting a message and re-sending it as a new message does not send a notification to the other users in the group or private chat, but they may notice that the message has been re-sent, so it's best to steer clear of re-sending messages that are completely different from the original one.

Another thing to be mindful of is that if you re-send a message that was sent before, Telegram will automatically change the timestamp of the re-sent message to be the timestamp of when it was re-sent, not the original timestamp. This means that the re-sent message will appear in the chat as being sent recently, not when it was actually sent previously.

Keep in mind that while this method allows you to edit or tg 下载 remove messages on The Platform, it's not a native feature for doing so, but it's a workaround to achieve similar outcomes. If you're in a group conversation where multiple people are sending messages rapidly, deleting and re-sending messages may not be ideal for avoiding distractions, especially if the other group members notice the removed message or re-send.
