Error binding to Google Document AI

[Wuz3t]

We are trying to get access token for our document ai processor.
Here is our configuration

vault write gcp/roleset/role-name 
project="proj-name" 
secret_type="access_token"
token_scopes="https://www.googleapis.com/auth/cloud-platform" 
bindings='resource "https://eu-documentai.googleapis.com/projects/<projnumber>" {roles = ["roles/documentai.viewer"
]}'

Error writing data to gcp/roleset/system-hpz-docai: Error making API request.

URL: PUT http://127.0.0.1:8200/v1/gcp/roleset/role-name 
Code: 400. Errors:

invalid resource "https://eu-documentai.googleapis.com/projects/<projnumber>": unsupported service/version for resource with prefix https://eu-documentai.googleapis.com/

Is this expected? How we can set up vault to recive access tokens for this API.

Thanks!
