✅
Just loop through Chart.instances
Chart.helpers.each(Chart.instances, function(instance){
alert(instance.chart.canvas.id)
})

If someone doesn’t want to iterate over instances array, then he can get instance directly from id like this.
const chart = Chart.getChart("canvas-id"); //where canvas-id is the id of a canvas
So now chart is your instance on which you can do the other operations. Reference here
