Responsive menu help

Hi, I am using the enigma theme for a client site and need help with the menu. The responsive toggle menu button appears sooner than I need it, I would like to display the text menu when the media screen is larger than the mobile size of 480px. Right now I get the toggle menu button instead of the menu text with media sizes as smaller than 800px or 768px to be precise. I tried to adjust the css, but then I run into issues with the toggle menu display that keeps vanishing on me. Is there an option to decide when the toggle menu button should appear?
