WixData querying services, how to get the session duration returned?

I am using wixdata to query bookings/services and have a custom page showing all the services available to book.

However, the data returned does not contain the session duration! How can i include this in the returned data?

I’m currently running:

wixData . query ( “Bookings/Services” )
// here i have tried to .include all kinds: session, sessionDuration, etc to no avail!
. find ()
. then ( ( results ) => {
console . log ( 'results: ’ , results );
$w ( “#serviceRepeater” ). data = results.items ;
} );
