How to read unread email with body and attachment using node-ews package - node.js

Question

I am able to send email using this node-ews package but I am not able find suitable example to read email from Inbox folder and get the body and attachments from the email.
I have gone through the Microsoft docs e.g. https://learn.microsoft.com/en-us/exchange/client-developer/exchange-web-services/how-to-work-with-exchange-mailbox-items-by-using-ews-in-exchange#get-an-item-by-using-the-ews-managed-api
but the examples are provided in C#, C++ or VB..
But I want to do this with Nodejs.

You can use following code to get emails from Inbox using FindItem function and then read each email using GetItem function
// Read emails from Inbox
var ewsFunction = 'FindItem';
var ewsArgs = {
'attributes': {
'Traversal': 'Shallow'
},
'ItemShape': {
't:BaseShape': 'IdOnly',
't:AdditionalProperties': {
't:FieldURI': {
'attributes': {
'FieldURI': 'item:Subject'
}
}
}
},
'ParentFolderIds' : {
'DistinguishedFolderId': {
'attributes': {
'Id': 'inbox'
}
}
}
};
// Itreate over all the emails and store Id and ChangeKey.
ews.run(ewsFunction, ewsArgs, ewsSoapHeader)
.then(result => {
// Iterate over the result and extract Id and ChangeKey of the messages and pass those to GetItem function to read messages
})
// For reading individual messages returned by FindItem (using Id and ChangeKey)
var ewsFunction = 'GetItem';
var ewsArgs = {
'ItemShape': {
'BaseShape': 'Default',
't:AdditionalProperties': {
't:FieldURI': {
'attributes': {
'FieldURI': 'item:Attachments'
}
}
}
},
'ItemIds' : {
'ItemId': {
'attributes': {
'Id': Id,
'ChangeKey' : ChangeKey
}
}
}
};
await ews.run(ewsFunction, ewsArgs, ewsSoapHeader)
.then(result => {
// Iterate over the result and extract meesage
})
