Given you have Plus, you could put the Logo image HTML in Main options > Menus > Primary Menu > Left HTML Box
Then add the rule below in the HTML Text color CSS+ box a few steps below that to remove default space above the image
{margin-top:0;line-height:0;}
Then Add the rule below in Main Options > FOnts and Custom > Custom CSS Rule box to shift the menu bar down on desktop
.is-desktop #nav-primary ul.wvrx-menu {margin-top:15px !important;}
That will also keep the logo to the right of the Hamburger menu on mobile.
If you don’t like that we can look at alternate solution
