      @Perlchamp very good… now, I didn’t test the code I wrote, so there are a couple errors…

      but you should be able to see that code in the developers window, sources tab,
      navigate on the left tree, modules, your module_name (which has to be perchamp,
      folder, filename and the register at the top) all have to match)

          @Perlchamp you shouldScreenshot at 2020-05-01 18-12-15.png see an error like this

          note that I put part of the module name in the filter field

                so, sam, everything is fixed :-)
                but now i don’t know how to handle the receiving data. i only need a little entry … don’t know how to handle this object-element. actually nothing is displayed except the header i configured …

                  @Perlchamp cool, now you’ve collected the data… you should be able to see the results on the exit from the notification handler…

                  now to tell MM to come get the stuff to display…

                  thats the self.updateDom() call

                  hey MM, get my stuff

                  then MM will call getDom()

                  I have implemented the module too

                  getDom: function() {
                  		var wrapper = document.createElement("div");
                  
                  		for(var birthday of Object.keys(this.active_birthdays)){
                  				for(var name of this.active_birthdays[birthday]){
                  					var m=document.createElement('div')
                  					m.innerText=birthday + ' '+ name
                  					wrapper.appendChild(m)
                  				}
                  		}
                  
                  		// pass the created content back to MM to add to DOM.
                  		return wrapper;
                  	},

                    @Perlchamp one thing to watch out for, getDom() will be called immediately, long before you have any data,
                    but you MUST return something… so an empty div works… (this is where that 'Loading…" message would be presented

                        this is the getDom-section where the data finally should be placed (perlchamp is for testing) :
