Dear support!

I am using Metronic 8.1.5 HTML theme and I would like to known if this version has the functionalities KTApp.blockPage, KTApp.unblockPage, KTApp.block and KTApp.unblock. If not, which is the equivalent for:

KTApp.blockPage({
overlayColor: '#000000',
state: 'primary',
message: 'Wait...'
});

KTApp.unblockPage();

KTApp.block('#col_sector', {
overlayColor: 'red',
opacity: 0.1,
state: 'primary' // a bootstrap color
});

KTApp.unblock('#col_sector');

Thanks
