It can be embarrassing when you mistype something but it's ok, we've all been there. Lucky for you, there's a way to edit your message so you can clarify what you meant to say!
Step 1: Hover over the message & select the pen icon to Edit.
Step 2: Correct the typos...
Step 3: And press enter (or click 'save') once you're sure it's correct.
Note: In case you change your mind, you can always back out at this step and press 'escape' if you don't want to edit the message (or you chose the wrong message to edit).
