Ẩn text rồi thay thế bằng CSS

Cách 1:

.fusion-secondary-header .fusion-mobile-selector::after {
    content: 'Login';
    padding-left:5px;
}
.fusion-secondary-header .fusion-mobile-selector span {
    display: none;
}
.fusion-secondary-main-menu .fusion-mobile-selector::after {
    content: 'Menu';
    padding-left:5px;
}
.fusion-secondary-main-menu .fusion-mobile-selector span {
    display: none;
}

Cách 2:

#toplevel_page_ab-system .wp-menu-name {
  text-indent: -9999px;
  line-height: 0; /* Collapse the original line */
}

#toplevel_page_ab-system .wp-menu-name::after {
  content: "Appointments";
  text-indent: 0;
  display: block;
  line-height: initial; /* New content takes up original line height */
}
