The crux of the issue is that cssOverrides is not directly available in the context of the styled component. To resolve this, you need to ensure that you pass cssOverrides directly when using the Launcher component.

The Solution: Passing Props Correctly

To fix the error, you need to do the following:

Pass the cssOverrides prop when you instantiate the Launcher component.

Here’s how you can do that:

This change effectively passes the cssOverrides prop down into your styled component, allowing you to utilize the styles defined in it without encountering the undefined error.

This ensures that cssOverrides is now defined and accessible in the styled component, resolving the error.

By passing properties correctly into your styled components, you avoid common pitfalls that might arise when working with React and Redux. This will not only improve your development experience but also enhance the maintainability of your code.

If you experience similar issues in the future, remember to check that you're passing props as intended, and happy coding!
