I have tried adding some styles to the panel header of the shoelace dialog. I could add a base style for the entire dialog., but adding a custom class to shadow root DOM is not actually taking it. Here's the code of what I am trying to do
Adding custom style to the element
Base styles for the dialog which is working
Custom styles which is not applying
All these styles are kept in a external css file.
What I can do to make it work? Please let me know. Thank you.
