Play Piano Chords in a score

In a recent MuseScore Cafe, there was a cheat card how to play chords in a score. But why can't MuseScure use this to actually play the chords?

I often get a score with Chords instead of a piano staff. Then I have to figure out first how does this chord sound on a piano and then I have to search for the right notes to play it like that (now i have the cheat card to help me but many people don't)

So it takes some time to add such a score to MuseScore, and I want to add the piano section to the score because I can hear the piano as support when I sing my part.

But there is this cheat card, In my mind, its now a small step to embed this inMuseScore so the right chord is played when the corresponding chord symbol appears in the score.
