Dark Mode in Linux Mint app image desktop

Hi, I started with Neo4j desktop in Linux Mint this morning. I downloaded the app image, and after some hurdles installed Neo4j Desktop. From first look, I like what I see. However, the main window is “light mode”, while the surround and sidebar are dark. As someone who prefers dark themes, for eye sake. I wonder if this can be done. There is no ‘appearance’ section in settings. Thanks for any advice.
