How to reverse adjustment from collections workbench

Summary:

Hi Team,

We are trying to reverse the adjustment in Fusion and upon checking the CCC i see there is a way provided.

However, I can perform this action only if i go to Billing> Transactions> Manage adjustment.

We want to do this from collections workbench. But I see that after creating an adjustment in collections workbench and if we try to reverse the way mentioned in the above CCC thread, Adjust button is greyed out.

Could you please let us know how we can reverse the Adjust from collections workbench? Because in our business it will be done by the collectors.
