Email Template Not Fetch in Email Through js args

Hello I have made an email Template and fetched fields name using Jinja Template. but when I send Email, details are not fetched properly it will send the Template format in Email as it is
and when I open an email Popup from the system it will fetch data properly
here is my code:
frappe.ui.form.on(‘Purchase Order’, {
after_workflow_action:function(frm) {
var email_id = cur_frm.doc.email_id;
var send_email_check=frm.doc.send_email
console.log(send_email_check)

   if(send_email_check==1){

    var supplier = cur_frm.doc.supplier;
    var name = cur_frm.doc.name;
    var date= cur_frm.doc.schedule_date;
    
    var template = frappe.db.get_value('Email Template', 'Purchase Order Approval', 'subject')
    console.log(template)
    
    var doc = frappe.db.get_doc('Email Template',null,{subject:'Purchase Order Approval'})
    .then(doc => {
        console.log(doc)

    
    
    frappe.call({
    method: "frappe.core.doctype.communication.email.make",
    args: {
        sender:'poojavadher24@gmail.com',
	    recipients:frm.doc.email_id,
	    subject: "Purchase Order " + frm.doc.name + " Confirmation",
	    doctype: "Purchase Order",
	    name: cur_frm.doc.name,
	    send_email: 1,
	    communication_medium: "Email",
	    email_template:"Purchase Order Approval",
	    content: doc.response,
	    
	  //  content: `Hello, Purchase Order has been Created ` +name+ ` for 
	  //  Supplier: ` +supplier+ ` 
	  //  End Date of this Order is ` +date+ ` 
	  //  Please Confirm that `,
	    
	
	  
	    
    },
   
    callback: function(r){
        console.log(r.message);
        }
    });
})

}
}

})
