Hello @satwik ,
yes, I included the dependency in in the app manifest.
The package.json file looks the same as the one of the npm package that you linked
Maybe there’s something wrong in my project structure? I’m working with git, but when I generated the app I had an error telling me that the folder wasn’t empty (because of the initial “.git” and “README.md” files), so I created the “app” folder and generated the custom app inside there.
