Why can't the sound just made be taken back?

Messages sent within 2 minutes can only be recalled. Messages sent over 2 minutes cannot be recalled, but you can delete the retransmission.

1, 5.3. 1 has added the recall message function, so if your version is too low, please upgrade first.

2. If you need to recall the message, press and hold the message you just sent, and a menu will pop up with the option of recall.

3. Click Recall to see the prompt, and the last message just sent will be recalled.

4. After clicking OK, you will see the prompt "You withdrew a message", and the message just now has been deleted from the chat record.

PS: When you withdraw the message, the other party will be prompted that you have withdrawn the message, although they can't see the message you sent.
