Use user email to observe user resource

[JeppeAlstrup]

Hi,

Similar to: https://registry.terraform.io/providers/PagerDuty/pagerduty/latest/docs/data-sources/user where it is possible to observe an already created user by just specifying the users email, I'm wondering if this is even supported?

It seems that currently, this can only be done by specifying the ID of the user and marking the management policies as observed, e.g.:

apiVersion: user.pagerduty.crossplane.io/v1alpha1
kind: User
metadata:
    annotations:
        crossplane.io/external-name: {{ $user_id}}
        {{ setResourceNameAnnotation "pagerduty-user" }}
    labels:
        testlabel: test
spec:
    providerConfigRef:
        name: default
    managementPolicies: 
        - "Observe"

I tried looking into the following section in the readme, but I cannot seem to map external-name to the email property.

Either way, since I need something similar for the team resource, and really want to get rid of my terraform provider, I would like to understand if this is actually supported out of the box - and if not, I guess it could be a neat feature to add to the provider.
