It is extremely importand that you change the firebase configs in both files and the vapiKey. Then remove all permissions for notifications where you have hosted your project.
Unregister the curren Firebase SW as he might be corrupted and stuck:
Also pls use serve for the local hosting. After that open your side press the button and copy the token here:
After sending your message you won't see a notification because we are handling it on y custom way so you will only see a log like in the first picture.
