Include icons on modal buttons

Question

Good afternoon, I am creating a modal that is already with all the perfect functionalities, but I need to include in the buttons the accept and cancel icons to leave more didactic for the user, but in jquery I do not know how to do this. The code I’m using to call the modal is this, I don’t know if there’s any other way to do this tbm.

$('#div_dialog_MostrarTexto').dialog({
    open: function(event, ui) {
        $(this).parents(".ui-dialog:first").find(".ui-dialog-titlebar-close").remove();
    },
    resizable: false,
    minHeight: 600,
    minWidth: 650,
    maxHeight: 600,
    modal: true,
    autoOpen: true,
    title: titulo,
    position: { my: 'top', at: 'top' },
    overflow: scroll,
    buttons: [
        {
            text: $('#doc_aceita_' + dadosDocumentos[idDocumento]).val(),
            disabled: false,
            image: "../img/confirmar.jpg",
            click: function() {
                aceitou(idDocumento);
            }
        },
        {
            text: $('#doc_recusa_' + dadosDocumentos[idDocumento]).val(),
            disabled: false,
            image: "../img/cancelar.jpg",
            click: function() {
                recusou(idDocumento);
            }
        },
    ]
});

Why it does not work with jquery icons?

If it is with following icons, I will search for images.

$('#div_dialog_MostrarTexto').dialog({
    open: function(event, ui) {
        $(this).parents(".ui-dialog:first").find(".ui-dialog-titlebar-close").remove();
    },
    resizable: false,
    minHeight: 600,
    minWidth: 650,
    maxHeight: 600,
    modal: true,
    autoOpen: true,
    title: titulo,
    position: { my: 'top', at: 'top' },
    overflow: scroll,
    buttons: [
        {
            text: $('#doc_aceita_' + dadosDocumentos[idDocumento]).val(),
            disabled: false,
            icons: { primary: 'ui-icon-check' },
            click: function() {
                aceitou(idDocumento);
            }
        },
        {
            text: $('#doc_recusa_' + dadosDocumentos[idDocumento]).val(),
            disabled: false,
            icons: { primary: 'ui-icon-close' },
            click: function() {
                recusou(idDocumento);
            }
        },
    ]
});
