Trying to use map cluster to group markers with the same coordinates

I'm using a plugin for leaflet.js called Map Cluster to group coordinates that are similar and the same. I've manually set multiple coordinates (lat, lang) on to the script. After running, markers with the same coordinates do not seem to get clustered together but only place on top of one another.

var map = L.map('mapid', {

            fullscreenControl: {
                pseudoFullscreen: false // if true, fullscreen to page width and height
            },
            
        }).setView([-40.99497,174.50808], 10);

        map.createPane('labels');
        map.getPane('labels').style.zIndex = 650;
        map.getPane('labels').style.pointerEvents = 'none';

        var positron = L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
                noWrap: true,
                maxZoom : 15
        }).addTo(map);

        var positronLabels = L.tileLayer('http://{s}.basemaps.cartocdn.com/light_only_labels/{z}/{x}/{y}.png', {
                pane: 'labels',
                noWrap: true,
                maxZoom : 3
        }).addTo(map);

		var markers = L.markerClusterGroup({ 
            spiderfyOnMaxZoom: false, 
            showCoverageOnHover: false,
            zoomToBoundsOnClick: false 
        });

        var southWest = L.latLng(-89.98155760646617, -180),
            northEast = L.latLng(89.99346179538875, 180),
            bounds = L.latLngBounds(southWest, northEast);

            map.setMaxBounds(bounds);
            map.on('drag', function() {
                map.panInsideBounds(bounds, { animate: false });
            });

		var markers = L.markerClusterGroup({ 
            spiderfyOnMaxZoom: false, 
            showCoverageOnHover: false,
            zoomToBoundsOnClick: false 
        });

        var plot = [
            ["7C6B07",-40.99497,174.50808],
            ["7C6B38",-41.30269,173.63696],
            ["7C6CA1",-41.49413,173.5421],
            ["7C6CA2",-40.98585,174.50659],
            ["C81D9D",-40.93163,173.81726],
            ["C82009",-41.5183,174.78081],
            ["C82081",-41.42079,173.5783],
            ["C820AB",-42.08414,173.96632],
            ["C820AB",-42.08414,173.96632]
        ];


        for ( var i = 0; i < plot.length; i++ ) {
            marker = new L.marker([plot[i][1], plot[i][2]]).bindPopup(plot[i][0], {autoClose:false}).addTo(map).openPopup();
        }

        markers.on('clusterclick', function (a) {
            a.layer.spiderfy();
        });

            }).setView([-40.99497, 174.50808], 10);

            map.createPane('labels');
            map.getPane('labels').style.zIndex = 650;

Add yours markers to one of your marker cluster groups instead of to your map.

Do not forget to add the group itself to the map.
