Send Activity Notification doesn't show up, can only see the badge

Question

I am using the /users/{userId}/teamwork/sendActivityNotification endpoint with the TeamsActivity.Send delegated permission to send an activity notification from a user to another user.

The notification is successfully sent, but I can only see the badge. Nothing more is shown. No text, no sound, no banners. The feed remains empty.

Here is my request to post the notification:

      .api(
        `/users/{userId}/teamwork/sendActivityNotification`
      )
      .post({
        topic: {
          source: "entityUrl",
          value: `https://graph.microsoft.com/v1.0/users/{userId}/teamwork/installedApps/{appId}`,
        },
        activityType: "missedCall",
        previewText: {
          content: "previewText.content",
        },
        templateParameters: [
          {
            name: "caller",
            value: "phone number",
          },
        ],
      })

Answer 1

It is quite strange that the notification content doesn't show up.
Using this sample we checked, and it does send the activity feed notification.
Could you please check once?
