I-9 Everify Onboarding Task clean up

Hello - we are looking for recommendation to assist in closing the candidate task status between (Pending, Open, In Progress, Complete).

A little back story - we are using the ICIMS-E-verify integration where  we choose the onboarding task in ICIMS - it triggers and invite from our I-9 platform to the candidate through the onboarding portal.  The candidate fills out their Section 1 information and submits to our I-9 platform.  Next step, the Employer (recruiter manger) follows a link in the I-9 E-Verify Screening Tab where they are re-directed into our I-9 portal to verify the Section 1 information and fill out Section 2.

The disconnect is that the task for the candidate (Employee) remains Open.

Is there a way to close that task?
