Testing Oracle Functions: cannot list apps

Summary

Always getting error Fn: [GET /apps][404] ListApps default &{Fields: Message:Path not found: GET /v2/apps}

I am absolutely new to oracle OCI. I started with the tutorials on creating an oracle cloud function.

I went through the tutorials (several times) setting up all configurations, policies, etc...

But, when I simply enter 'fn list apps' in the console I always get the error Fn: [GET /apps][404] ListApps default  &{Fields: Message:Path not found: GET /v2/apps}

Any further commands like deploys and invokes give the same error.

Does anybody have an idea what setting, configuration might be wrong or what else could be wrong ?
