You can edit the configuration of a GCP account to update the Role ARN.

You can't change the account that ZEN Master is linked to, you can only update the permissions that apply to the original account.

To edit a GCP Account:

In GCP, adjust the permissions for ZEN Master and generate a new Service Account Key File.
In ZEN Master, on the Configuration > Google GCP screen, click on the Edit icon for the desired account.
The Edit GCP Account window opens.
You can edit the Name if you would like.
Click Choose File and navigate to the new Service Account Key File.
Click Save.
The new settings are applied.
