How can we send mail in Oauthentication 2.0?

Hello,
We are Bonita users.
Our company uses office 365 (AzureAd ) as mail sending server. Office 365(AzureAd ) system has now disabled using basic authentication. We have created an application to send mail from AzureAd portal. We need to send e-mails using the information of these applications.
We were actively sending mail using the smtp protocol as follows.

And since it has switched to the Oauthentication 2.0 system, we can no longer send mail with the smtp protocol we explained above.
