Accidentally deleted sync account

Accidentally deleted sync account

Hello,

We accidentally deleted the user account that was used to generate the Zoho Services Communication key for syncing between desk and CRM. When we try to delete the sync integration to build a new one with a new ZSC key, it tells us we need to enter a valid ZSC key, but the person who generated that key is no longer with the company and his account has been deleted from Zoho.

Any idea how to fix?
