How to bulk update to inactivate worklist access

Hi,

Worklist Access was enabled initially and hundreds of users have created/granted access to other users (records in FND_GRANTS).

Now business want to remove this option due to audit concerns.

we can hide the Worklist Access link (Tip) from users but we need to inactivate the existing data.

Is there any API or Sysadmin screen available to delete or inactivate the workliast access for all users (as it's not feasible to ask all those users to end-date or delete the worklist access in-time)

please advice if there is any API or page avaialable or do we have to do direct Update of FND_GRANTS to populate end_date??
