How to edit host file for google calendar on node red

Hello

I'm running node red on a cerbo gx (running on Venus OS) device and I'm trying to setup a google calendar node. At the moment I have everything configured in the google cloud (created app, enabled API, got the credentials) but 1 last thing I have to do is " You will need to edit your hosts file and add an entry for node-red.example.com that points to 192.168.1.139"
Now is the question, how do I do this correctly?

Thanks in advance :wink:

That isn't a node-red question, but taken at face value then you need to edit the file \etc\hosts and add a line containing
192.168.1.139 node-red.example.com
