O365 event seem not include enough information

CG Version:

o365 : Business Basic trial 30 days lab.


HI All

   I configure O365 and Azure AD to collect O365 & AD events.

it seem collect event and well.

But I fine these events seem not include all information.

For example, I modify a mailbox , clear the mailbox delegation (like send as or send on hehalf)

the event show which admin account modify this account...but it does not show what setting or parameters been set.

Is it Azure still not provide enough information let CG collect or my CG need modify some settings to collect more information like my example ?
