Invoice in Zoho Books via zapier

Invoice in Zoho Books via zapier

I am trying to setup integration from Weemss to Zoho Books through zapier to create and send an invoice.
The parameters does include Invoice status =Paid, which is correct.
However, the invoice remains in Draft, I would like to have it sent by email, with the status of being paid.
Also I did not find a way to add VAT
Thanks for your help
