Sharepoint O365, Direct Send email from a Console Application

Hi All, 

I am trying to send a E-mail from a console app, all of my receivers are in O365(internal users) so i want to send Direct email, as it does not require a account with mailbox as discussed in the article(https://support.office.com/en-us/article/How-to-set-up-a-multifunction-device-or-application-to-send-email-using-Office-365-69f58e99-c550-4274-ad18-c805d654b4c4?ui=en-US&rs=en-US&ad=US). But i am not able to figure out how to do that. I am not even sure that if it id even possible.

PS: my console app is a client side application, which accesses data from Sharepoint using CSOM.

Thanks in advance.
