I created a project as non-admin user via the cloud shell with the following command "gcloud projects create vpclabacg2".
But everything seems blocked, when I try to link the project to my billing account I get " User […@gmail.com] does not have permission to access projects instance [vpclabag2] (or it may not exist): The caller does not have permission". Thanks for your answers.
In the Cloud Playground, you must use the provided project. To see what can be done in the GCP Sandbox, see https://help.acloud.guru/hc/en-us/articles/360001389276?_ga=2.240111747.167065253.1612774954-542753773.1598953645
For activities outside of what the sandbox can provide, we recommend a free tier account. If you are working in your own personal account, see: https://cloud.google.com/iam/docs/granting-changing-revoking-access
