Feature enhancement to add the Contacts from child accounts as External Attendee in an Activity.

Hi Team,

Contacts from Child accounts are not showing up when trying to add them as External Attendee in an Activity.
Example: ABC Tech is a parent of XYZ Tech. When we try creating an activity in XYZ Tech, I can see the person: “Shyam” there, this person is company person to XYZ Tech so he is showing in external attendee, this is expected, but while trying to do the same at parent level (for the company: ABC Tech), I am not able to see Shyam.

Thank you.
