The problem is that the URL returns a failure so it cannot be used to enable the API:

https://console.developers.google.com/apis/api/cloudshell.googleapis.com/overview?project=google.com:cloudsdktool -> The API "cloudshell.googleapis.com" doesn't exist or you don't have permission to access it

I posted the problem at https://cloudplatform.googleblog.com/2018/03/introducing-the-ability-to-connect-to-Cloud-Shell-from-any-terminal.html and https://cloud.google.com/sdk/gcloud/reference/alpha/cloud-shell/ssh although on the latter, the post somehow is not visible.

Only a +1 on https://plus.google.com/+AdrianMariusPopa/posts/XJm7QPFDVHq but no answer yet.

Select/Enable the correct project both in the GUI and console..
