[Cerrado] Change font of menu items on 2nd language website

Hello, I'm trying change the font of menu items only on the 2nd language website (Thai), none of my codes worked, so a WPML support team member kindly suggested this:

html:lang(th) .font-family-menu, .menu-container:not(.grid-filters) ul.menu-smart, .top-menu.top-menu-enhanced ul.menu-smart, .menu-container:not(.grid-filters) ul.menu-smart a:not(.social-menu-link):not(.vc_control-btn), .top-menu.top-menu-enhanced ul.menu-smart a:not(.social-menu-link):not(.vc_control-btn), .uncode-menu-additional-text, .burger-label, #masthead .overlay .overlay-search-wrapper .search-container form .search-container-inner input {
font-family: 'Prompt' !important;
}

Unfortunately, it implemented the font on both languages.
