How to connect Node service with Office 365 Mail Box

I’m facing issues while trying to read mail from Office 365 account.
Below is the code I’m using:

const EWS = require(‘node-ews’);

// exchange server connection info
const ewsConfig = {
username: ‘myuser@myDomain.com’,
password: ‘mypassword’,
host: ‘https://outlook.office365.com/owa/myDomain.com/’,
auth: ‘basic’
};

// initialize node-ews
const ews = new EWS(ewsConfig);

// define ews api function
const ewsFunction = ‘ExpandDL’;

// define ews api function args
const ewsArgs = {
‘Mailbox’: {
‘EmailAddress’:‘publiclist@domain.com’
}
};

// query EWS and print resulting JSON to console
ews.run(ewsFunction, ewsArgs)
.then(result => {
console.log(JSON.stringify(result));
})
.catch(err => {
console.log(err.message);
});
