Issue while searching for Internal Collaborator from a task within timeline activity

Hi Team,

<Internal Collaborator Access>

For an internal collaborator, we are allowing CTA to be assigned from cockpit but a task created within a timeline task does not fetch the user while selecting the user as task owner.

Replicated in local:

Are we allowing internal collaborator to be owner of CTA/task from cockpit? If so, why can’t we do the same for a task created in timeline activity?

Thanking in advance!
