Zoho Finance DELETE Scopes in Flow Connections

When creating Flows related to Zoho Finance data, a big, missing piece of API Connections is the DELETE scope. I cannot use Deluge to delete anything—records, attachments, etc. I am "not authorized" to perform that operation, even when I select "all triggers/actions" for a given API connection.

I'm not missing anything, right? It's just not available yet? This would be really nice to have!

Use case, specifically, is that, when an Invoice in Inventory is updated, we need to re-generate various PDFs related to the record and attach those to the invoice, but only AFTER deleting whatever attachments were already present. We can do this in Inventory itself but there are other pieces (connecting to Google drive, some branches) of the Flow that need to stay in Flow......
