@tjtanjin Could you help me with the failing tests? I went through the logs and as far as I understand the test suite fails due to an invalid element type error in TestChatBotProvider. The root cause is an undefined ChatIcon component in DefaultSettings.tsx or some type of import error. This doesnt really have anything to do with my file. Could you verify once if I am right or am I missing something.
