Example request

cURL
curl --request GET \
     --url "https://telemetry.betterstack.com/api/v2/dashboards/1234/charts/18718/comments/1442" \
     --header "Authorization: Bearer $TOKEN"


user_email is returned only when the comment has an author. A comment created with an API token has none, so the field is omitted. See List all comments on a chart for what the other attributes mean.
