What is the database name of an InfluxCloud bucket used to configure a grafana cloud datasource?


I have configured a cloud influxdb (working). I now would like to use this as a data source in grafana.
I configured a new grafana datasource as an influxdb type but I do not find the “database name” to configure in the grafana form. I tried the bucket name (and other variations) but no success.

Where is the name of a cloud influxDB database ? (to use in grafana)
