We are trying to develop a outlook addin for new outlook and testing using Outlook 16.75.2 on Mac desktop app.
We have "OnMessageSend" / "OnAppointmentSend" working to get javascript callbacks when a mail is sent/replied/forwarded and appointment is created.
But when we forward the meeting invite or cancel the meeting, we dont have a Event type to receive javascript callback.
I tried all the event types listed here

Sample events from manifest.xml
<LaunchEvent Type="OnNewAppointmentOrganizer" FunctionName="handleSendMail" SendMode="SoftBlock"/> <LaunchEvent Type="OnMessageAttachmentsChanged" FunctionName="handleAttachMail" SendMode="SoftBlock"/> <LaunchEvent Type="OnAppointmentAttachmentsChanged" FunctionName="handleAttachMail" SendMode="SoftBlock"/> <LaunchEvent Type="OnMessageRecipientsChanged" FunctionName="handleSendMail" SendMode="SoftBlock"/> <LaunchEvent Type="OnAppointmentAttendeesChanged" FunctionName="handleSendMail" SendMode="SoftBlock"/> <LaunchEvent Type="OnAppointmentTimeChanged" FunctionName="handleSendMail" SendMode="SoftBlock"/> <LaunchEvent Type="OnAppointmentRecurrenceChanged" FunctionName="handleSendMail" SendMode="SoftBlock"/> <LaunchEvent Type="OnInfoBarDismissClicked" FunctionName="handleSendMail" SendMode="SoftBlock"/> <LaunchEvent Type="OnMessageSend" FunctionName="handleSendMail" SendMode="SoftBlock"/> <LaunchEvent Type="OnAppointmentSend" FunctionName="handleSendMail" SendMode="SoftBlock"/> <LaunchEvent Type="OnMessageCompose" FunctionName="handleSendMail" SendMode="SoftBlock"/> <LaunchEvent Type="OnAppointmentOrganizer" FunctionName="handleSendMail" SendMode="SoftBlock"/> <LaunchEvent Type="OnMessageFromChanged" FunctionName="handleSendMail" SendMode="SoftBlock"/> <LaunchEvent Type="OnAppointmentFromChanged" FunctionName="handleSendMail" SendMode="SoftBlock"/> <LaunchEvent Type="OnSensitivityLabelChanged" FunctionName="handleSendMail" SendMode="SoftBlock"/>`
