CF7 with Elementor Popup Builder

@takayukister I am having the same issue. Seems The CF7 scripts.js are rewritten with pure JS. So the previous jQuery initForm function is not available.

Please guide us with a reference to how can we initiate the form with pure JS.

Here is my current code for initiate the form in an Ajax popup.

+(function($) {
    var WPB_Quote_Button = {

        initialize: function() {
            $('.wpb-get-a-quote-button-form-fire').on('click', this.FireContactForm);
        },

        FireContactForm: function(e) {
            e.preventDefault();

            var button  = $(this),
            id          = button.attr('data-id'),
            post_id     = button.attr('data-post_id'),
            form_style  = button.attr('data-form_style') ? !0 : !1,
            width       = button.attr('data-width');

            wp.ajax.send( {
                data: {
                    action: 'fire_contact_form',
                    contact_form_id: id,
                    wpb_post_id: post_id,
                    _wpnonce: WPB_GQB_Vars.nonce
                },
                beforeSend : function ( xhr ) {
					button.addClass('wpb-gqf-btn-loading');
				},
                success: function( res ) {
                    button.removeClass('wpb-gqf-btn-loading');
                    Swal.fire({
                        html: res,
                        showConfirmButton: false,
                        customClass: {
                            container: 'wpb-gqf-form-style-' + form_style,
                        },
                        padding: '30px',
                        width: width,
                        showCloseButton: true,
                    });
                    if(typeof wpcf7 != 'undefined'){
                        wpcf7.initForm( $('.wpcf7-form') );
                    }
                },
                error: function(error) {
                    alert( error );
                }
            });
        },

    };

    $(function() {
        WPB_Quote_Button.initialize();
    });
})(jQuery);
