sweetalert2: use as preloader of content - sweetalert

Question

I would like to use the sweetalert2 this way:
$('.preloaderContent').click(function(e) {
e.preventDefault();
swal({
title: "Data collecting....",
text: "Please Wait!",
type: "info",
showLoaderOnConfirm: true,
preConfirm: function() {
return new Promise(function(resolve) {
$.ajax({
type: "get",
url: '/reports/test',
success: function(response){
$('.page-content').html(response);
}
})
});
}
});
});
How can I use 'swal.clickConfirm()' to start the loading without the need of letting the user hit the 'OK' Button?
And how can I close the swal window after all content is loaded?
Thanks so much!
!!! UPDATE:
This way it is working for me:
$('.preloadData').click(function(e) {
e.preventDefault();
swal({
title: "Collecting data....",
text: "Please wait just one moment",
type: "info",
showLoaderOnConfirm: true,
onOpen: function(){
swal.clickConfirm();
},
preConfirm: function() {
return new Promise(function(resolve) {
$.ajax({
type: "get",
url: '/x/xx/',
success: function(response){
$('.page-content').html(response);
swal.closeModal();
}
})
});
},allowOutsideClick: false
});
});
