Fix Kitchen Drawer

We would like some help fixing a kitchen drawer. The piece connecting the front of the drawer has fallen out (photo attached) and cannot be reattached back in any obvious way. As a result, the front of the drawer has become detached, as shown in the photos. The same part on the other side of the drawer has also come loose so we need both sides fixed. We do not have any new spare parts at hand as we are not sure what they are called or where to purchase them. We would appreciate any help with fixing the drawer. We are located in the IFSC area in Dublin 1 City Centre. The ideal time for us is any weekday afternoon (after 12pm).
