SIEM Data RBAC: Unable to create data access scope

Hi,

I am trying to apply my terraform code to create access scopes in SecOps SIEM and I get the following error even though the service account running this has the Chronicle API admin and Security Admin roles assigned:

│ Error: Error creating DataAccessScope: googleapi: Error 403: Permission 'chronicle.dataAccessScopes.create' denied on resource '//chronicle.googleapis.com/projects/<project name>/locations/europe-west3/instances/<customer ID>' (or it may not exist).

│ Details:

│ "resource": "projects/<project name>/locations/europe-west3/instances/<customer ID>"

│ },

│ "reason": "IAM_PERMISSION_DENIED"

│ ]

What am I missing please?

Thanks
