REST APIs for ODA Integration with FCCS Task Manager (Tasks, Schedules, Actions)

Hello,
I am working on a Proof of Concept to integrate Oracle Digital Assistant (ODA) with FCCS Task Manager, and I would like to enable the following capabilities through APIs:

Retrieve tasks assigned to the logged‑in user
View “My Tasks”
Retrieve tasks where the user is an approver
Retrieve tasks where the user is an owner
Display the schedule summary for the logged‑in user
Display the schedule summary for a specific user (e.g., user XXXXX)
Submit a task
Approve a task
Add a comment to a task
View task comments

Could you please confirm whether these actions are supported?
