How to build a button which was created in CRM using CreateUsingTemplate functionality into an automated function?

Scenario: I have created a button in my CRM, that uses the CreateUsingTemplate functionality. I need to build this into an automated function. Is it possible to use a CRM sendMail function to select my email content template and attach the record I have created in Sign for the customer to complete?

1. The email templates in Zoho Sign can be customized in terms of design and HTML from our app's user interface. This can be achieved by creating a custom template by going to Settings > Admin > Email templates.
   
2. These custom templates then will be applied across all the integrations when sending out documents for signatures. If not, a completely customized email in the HTML format can be passed into your Deluge code.
   

The implementation for this is as follows:

1. In the createUsingTemplate task of your Deluge function, set the is_quicksend parameter to false. This creates a draft instead of sending the document out using the default email template.
   
2. Use the submitRequest task to send the document out for signing. When passing the data for this task, you must add the mail_template key in the actions array for each action -> data > requests > actions > mail_template.
3. Pass the customized email content in the HTML format into this parameter. The content must contain the tag $LINK_TO_SIGN$, which will be replaced by the signing link when the email is sent out. The tag can be in a button or hyperlinked in any other HTML element.
