Creating a dashboard with buttons (cards)

I’m looking for a way to give my daughter access to Google assistant. I thought that maybe she could have her own dashboard that she could use to start Elmo videos on YouTube or a kids song in Spotify using a card. Not sure if it’s the best way but could some one suggestion on that? Is the dashboard card the right way to go?

I found a solution using a zigbee button, deconz and an automation that is triggered by the button press event and then uses the media_extractor service to play a youtube video. if anyone wants to know more specifically how to do it, let me know.
