How can I make this work?

Hello EV charging experts, I need some advice. I bought this charger for my wife: https://www.amazon.com/EVIQO-Level-EV-Charger-Chargers/dp/B0BZRTD9VS/

Socket in garage: https://i.imgur.com/6aAkMmD.jpeg

Then I found out it uses a NEMA 4 prong 14-50 connection, but as you can see in the above picture, our garage has a 3 prong NEMA 6-50R socket. Is there a proper/safe way to make this work with an adapter without starting a fire, causing electrical issues, or damaging the charger? Or do I need to buy another charger? I'm having a hard time finding one that uses a NEMA 6-50R plug, and I'm not sure why our builder chose this receptacle when almost all chargers utilize 14-50.
