Office JS API for checking if email is encrypted or not

[pza-dev-brcm]

We are using ItemSend event in outlook add-in; In which we monitor email contents like - subject, body, recipients, attachments and based on policies defined we decide whether to allow or block the email.

As per our requirement, we want to know if the email is encrypted.
Also it will be helpful if we get more information like if the email is encrypted then with which flag it is encrypted like (Encrypt Only / Do Not Forward / SMIME) ?

Is there any API currently available for this in Office JS?

Note:
Currently add-in get's invoked if email is encrypted with (Encrypt Only / Do Not Forward).
We want to somehow know in the add-in that email is encrypted.
