Message Icons Not showup in Form validation

My Solution is to Work out a CSS:

/Validierungs-messages/
.elementor-message::before {
content: “\f164”;
display: inline-block;
font-family: fontawesome;
font-weight: 400;
font-style: normal;
vertical-align: middle;
margin-right: 5px;
}

.elementor-message.elementor-message-danger::before {content:"\f06a"; }
