Authenticated User Timeline Workbook - Parse Error

[jackwagons]

The Authenticated User Timeline Workbook does not escape UserId in Session Timeline sec.

KQL snippet:

set query_take_max_records=10001;set truncationmaxsize=67108864;
let monthName = (month:int) {
case(
month == 1, 'January',
month == 2, 'February',
month == 3, 'March',
month == 4, 'April',
month == 5, 'May',
month == 6, 'June',
month == 7, 'July',
month == 8, 'August',
month == 9, 'September',
month == 10, 'October',
month == 11, 'November',
month == 12, 'December',
''
)
};
union customEvents, pageViews
| where timestamp > ago(1d)
| where user_AuthenticatedId == 'domain\testuser' // needs to be escaped
| where name in ('') or '' in ('*')
| summarize Activities = count(), Start = min(timestamp) by SessionId = session_Id
| order by Start desc
| project ['Session Start'] = strcat('⌚ ', monthName(monthofyear(Start)), ' ', dayofmonth(Start), ', ', tolower(format_datetime(Start, 'h:mm tt'))), Activities, SessionId
//'⌚'

Is the expectation that the source data is responsible for escaping?
If not, is there an accepted pattern or utility in other Workbooks?

Happy to submit a PR based on feedback.

@MSKaiLian i think this is an appinsights template, just needs to have that parameter use :escape in the query like {parameterName:escape} ?
