Send targetedMeetingNotification to anonymous users using bot

Hey, I cannot understand if it is possible to send a targetedMeetingNotification to an anonymous user.

I added this to my app manifest:

  "meetingExtensionDefinition": {
    "supportsAnonymousGuestUsers": true
  }

When I join a call with an anonymous user, I do get a notification but it says there is a problem reaching the app (It works with external and organization users).

Is there any way to solve this? Or it doesn't work by definition?

    @Shahar Sonsino - targetedMeetingNotification are available only for Microsoft Entra users and not for anonymous users.
