The default UI for Grafana Tempo is Grafana, so we should also set the Grafana URL in the Kiali configuration, such as this example:
Kiali will use the _external_url_ to redirect to the Tracing UI, in the "View in tracing" links.
In Tempo, by default, the _url_format_ is set to _grafana_. This will use a particular url path and query for each link. The default UI for Grafana Tempo is Grafana, so it will use the _external_url_ set in the Grafana section, such as this example:

```yaml
spec:
external_services:
grafana:
internal_url: http://grafana.istio-system:3000
enabled: true
external_url: https://grafana.apps-crc.testing/
```

It is also possible to set _url_format_ to "jaeger". In that case, Kiali will use the _external_url_ set in the tracing section, and the url path and query will be following the Jaeger UI format.
