I’m new to strapi / node.js, can I integrate this with my own html/css/js code? either in the file with the html extension or in the file with the ejs extension. I started in VSCode to make a node.js application and I managed to integrate my html code in ejs files but I still need to use strapi to have unique passwords, I use strapi for the mobile application, I want the web part to have a custom design with certain actions dictated by custom js scripts/plugins
