I am looking for public facing document on applySentivityLabel to Emails or any internal Microsoft API endpoint that can be used to apply Sensitivity Label created in purview.

As an interim solution I tried using workaround provided here: https://learn.microsoft.com/en-us/answers/questions/681331/set-sensitivity-label-on-mail-message-using-graph; However this seems to limit only to apply importance label; not to apply custom label with Encryption. In addition I tried following and api returns error
