Bot framework V4 how to add facebook receipt with discount - node.js

Question

Is it possible to use the Discount option from Facebook Messenger's Receipt Template with Bot Framework V4?
Because I tried searching the samples, but they require string values, while the Facebook Template requires arrays.
Example:
"adjustments":[
{
"name":"New Customer Discount",
"amount":20
},
{
"name":"$10 Off Coupon",
"amount":10
}
],

Facebook Templates can be sent using ChannelData. Here is an example of a receipt template with adjustments:
await context.sendActivity({
text: 'Receipt',
channelData: {
"attachment":{
"type":"template",
"payload": {
"template_type": "receipt",
"recipient_name": "Stephane Crozatier",
"order_number": "12345678902",
