Once I added apollo-angular and @apollo/client to my project, I quickly realized that I no longer needed them. However, simply using "npm uninstall apollo-angular" and "npm uninstall @apollo/client" only removed the main folders but left behind other Apollo related files.
Even attempting to uninstall all the remaining Apollo folders in node_modules, such as apollo-cache, apollo-client, apollo-link, apollo-utilites, among others, had no effect.
I also tried manually deleting the folders, but encountered authorization issues and knew this was not the correct approach.
