Oluwatobi I'll like to insert a chat button that shows in all pages in FOSSBiling, I tried checking the settings but there not something like that I can find, is there a way to do this and when FOSSBiling is updated it will still retain the code?
BelleNottelling If all you need to add is JavaScript, Huraga allows you to add JS through the theme settings, otherwise you'd need to edit the layout_default.html.twig in the theme to add it in
