Create Reminder reports: "Unable to reach app. Please try again."

Describe the bug

We are trying to setup reminders with the schedule functionality, but this results in an error.

The error in Microsoft Teams states: Unable to reach app. Please try again. Also at the same time a message is posted saying: Activity Id: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx. Something went wrong!

We have added the app to our organization like 2 years ago, and the settings are like this:

To Reproduce

Steps to reproduce the behaviour:

1. Add the Github bot to the MS Teams Channel.
2. Finish the Authorization flow for the bot by running @github signin.
3. Add a subscription to our repo by running @github subscribe <orgname>/<reponame>.
4. At this point events are being received in the channel.
5. Then we enable the schedule functionality for receiving reminders for open issues etc. by running @github schedule <orgname>.
6. At this point we receive a Card with a button we can click called Create new reminder. But instead of getting a UI dialog the bot returns Activity Id: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx. Something went wrong!.

Expected behaviour

We expect to see this pop up:
