I'm trying to do a very simple communication between ipcRenderer and IPCMain but it's not working ! can someone tell me why ?

GALLERY.JS

const { ipcRenderer } = require("electron");


document.addEventListener('DOMContentLoaded', (e) => {
    ipcRenderer.send('test');
});

I really don't understand why nothing is printed in my console

GALERYCONTROLLER.JS

const { ipcMain} = require('electron');
const userId;
const Axios = require('axios')



ipcMain.on('test', (e) =>{
    console.log('droneDataGallery received')
   })

});

gallery.ejs

<link rel="stylesheet" href="../assets/css/GalleryPage.css"></link>

<div class='galleryPage'>

</div>

<script src="./../assets/js/gallery.js"></script>

Thanks a lot for your help !
