First add this Code into each Tab Title

<span class=”custom-font-sec-h”><i style=”color: #000000; margin-right: 10px; font-size: 20px;” class=”fas fa-minus custom-font-h”></i><i style=”color: #FF0000; margin-right: 10px; font-size: 20px;” class=”fas fa-plus custom-font-h”></i><span/> Tab #1

Then Add this into the Advanced CSS for the Tabs

.elementor-active .custom-font-h:nth-child(1){

    opacity: 1;

    transition: all 0.3s ease;

    background: #000000;

    color: #fff !important;

    font-size: 16px !important;

    padding: 4px 5px;

    border-radius: 50%;

}

.custom-font-h:nth-child(1){

    opacity: 0;

    transition: all 0.3s ease;

}

.elementor-active .custom-font-h:nth-child(2){
