How can I re-enable my Steam Deck display in Desktop Mode?

I followed the instructions in this post to disable my Steam Deck's display when in Desktop Mode which is basically the following: > by going into settings > display configuration > device (laptop screen) > unchecked enabled & primary But now my issue is: How do I re-enable it again? The display doesn't show up in the display configuration settings anymore. I see other people in that same post from above are also having the same issues where they don't know how to re-enable the display after disabling it. --- This is what I see in my display settings: I only see my two external displays. My Steam Deck's internal display isn't here anymore after I've disabled it. So I don't know where to find and enable it again. --- How can I turn my Steam Deck's display on again when in desktop mode?
