Hello, I'm trying to use zulip bot. I followed the example from [this page](https://zulip.com/api/configuring-python-bindings#download-a-zuliprc-file) and tried to run the simplehelloworld bot with the following command:

zulip-botserver --config-file helloworld/zuliprc --bot-name=helloworld

I downloaded thezuliprc file from the Zulip bot page, but it doesn't contain atoken field. However, when I run the botserver, I get the following error:

Error: Your Botserver config file `helloworld/zuliprc` has a missing option `token` in section `api`!You need to add option `token` with appropriate value in section `api` of `helloworld/zuliprc`

The linked documentation doesn't mention anything about atoken either. How should I resolve this?
