If I click the link https://console.dialogflow.com/api-client/#/agent/07872f08-081d-4724-bd2e-b218061fbc5a]. , there is no agent and also this error: IAM permission 'dialogflow.agents.get' on 'projects/07872f08-081d-4724-bd2e-b218061fbc5a].' denied. IAM permission 'dialogflow.agents.get' on 'projects/07872f08-081d-4724-bd2e-b218061fbc5a].' denied. shows up.

Removing lien using gcloud shell also doesn't work.

gcloud endpoints services delete 07872f08-081d-4724-bd2e-b218061fbc5a]
Are you sure? This will set the service configuration to be deleted, along with all of the associated consumer information. Note: This does not immediately delete the service configuration or data and can be undone using the undelete command
 for 30 days. Only after 30 days will the service be purged from the system.

Continue anyway (Y/n)?  Y
