As of the 2018.4.9 update, you can bring up the owner's manual, click on locks, click on doors, scroll down to the part on opening the door from inside, and leave it visible on the screen.
That will leave a valet with a clear picture of the button and a hard to miss explanation. I'd be curious to see what sort of results people get by doing this and whether it prevents seeing a message that the emergency handle was used.
