Also, do you want it to be permanently visible on the bottom of the message input box?

My Mattermost doesn’t show the reference as in your screenshot.

@Babbles From one of your earlier comments you were saying that the help guide is not visible at all even after entering few characters.

Is that the case? Or you want to have the help guide on by default even when there are no characters entered?
