Firebase Token issue settingup Chat21

We are currently getting the following error when setting up Firebase: The custom token corresponds to a different audience.
We have double checked our API details and have spoken to Google Firebase support and they are suggesting that it could be an issue with how chat21 has integrated firebase. Does anyone have any recommendations / suggestions?

Thanks in advance
Justin

Have you installed Tiledesk using Docker-compose or Kubernetes?
Can you send me a screenshot?

Hi
We are currently running it locally via ng serve --prod
Thanks
Justin
