Link CRM attachment fields to Form when page open

Link CRM attachment fields to Form when page open

Hello, 

The goal is to display the attachment (or a value near the attachment) field in the Form, when linked to the CRM attachment field with content

I created a form and linked it to the Account module

In the "Builder" part, when adding Zoho CRM field, we can map all fields except the attachments
In the "Integrations" part, in Zoho CRM, we can map attachments

At the end, the attachment fields are not filled 

Do you have a solution for this?
