I'm not able to delete any existing app.

To delete an existing app (which we call a table in Clay), you can follow these steps: 1. In your workspace, click on the ... icon next to the table you want to delete. 2. Select Delete from the dropdown menu. 3. Confirm the deletion when prompted. Alternatively, you can delete a table from within the table itself: 1. Click on the table name to access the table settings dropdown. 2. Select Delete and confirm your choice. If you accidentally delete a table, you can recover it from the Trash: 1. Click the Trash icon in your workspace. 2. Select the table you want to recover. 3. Click the ⟲ icon to restore the deleted table. If you need further assistance, please request human help by clicking on "Talk to a person".
