In my custom connector, for one of the actions, I require user input. For this required field, I would like to support type ahead search capability. This is similar to the behavior in Send an email (V2) action of Office 365 Outlook connector, where, when users start typing a name in the 'To' field, all matching accounts are shown in a dropdown.
Is there a way to define this behavior in the custom connector schema? Any help will be really appreciated.
