Hide HUD action?

I have an action that shows "MUTE" on the HUD-overlay. I have another action that shows "UNMUTED." I set "MUTE" to be on screen for 3000 seconds (basically ON all the time once triggered), and set "UNMUTED" to be on screen for 1 second.

Unfortunately, each trigger spawns a new HUD, instead of re-using the same HUD element, so after my UNMUTE HUD fades out, the MUTED HUD remains on screen.

Is there a workaround for this? If not, I think we need to either use/update the same HUD element with different text, etc, or have an action that is "Hide HUD."
