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: Select the gear icon found on the right side of your susceptible message and click 'Edit.'
Step 2: Correct the typos...
Step 3: And press enter (or click 'save') once you're sure it's correct.
Incase 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).
Just like that, your message says what what you intended it to all along.
