How to show current approval status to submitter using REST API

Summary:

Once user submitted a business process it will trigger PCS flow and route to multiple users for approval.

By using /ic/api/process/v1/tasks REST API, we can get data for the tasks with below status.

Valid states: ASSIGNED (Default), COMPLETED, SUSPENDED, WITHDRAWN, EXPIRED, ERRORED, ALERTED, INFO_REQUESTED.

ASSIGNED status, will show response to assignee who is going to take action. But how we can show that entry to submitter so that he/she aware of the current approver.

As a submitter if I want to see the over all approval history of a process since submission or current status, do we have any REST API ? Please advise.
