@mikael-navegador Hello, Mikael. You can add your own website apps to the Opera sidebar. First, go to opera://flags using the address bar. Then, in the search bar type in "sidebar". After that, find "Custom user sites for browser sidebar" and change it to "enabled." Now, restart the browser and go to the options of the sidebar (three dots in the left bottom part of the sidebar). Find "add a panel of custom websites" and add a new one. Where you have to enter the URL, enter the following https://discord.com/app

That would be it. I hope it works fine for you.
