Azure Bot Framework - GroupMe bot configured but cannot add to group or find bot

[oddrationale]

Problem Summary

I've successfully created and deployed an Azure Bot Framework bot that works in Web Chat, but I cannot figure out how to actually use it in GroupMe after following Microsoft's configuration instructions.

What I've Done

1. Created a simple Echo bot
2. Deployed the bot with messaging endpoint: https://[myhost]/api/messages
3. Created an Azure AI Bot Service resource
4. Configured the messaging endpoint in Azure
5. Verified bot works in "Test in Web Chat" - it responds correctly ✓
6. Followed Microsoft's documentation to configure GroupMe channel
7. Created a GroupMe application at dev.groupme.com
8. Set Callback URL to: https://groupme.botframework.com/Home/Login
9. Entered Access Token and Client ID in Azure Bot Service → GroupMe Channel Configuration
10. GroupMe channel shows as "Healthy" in Azure

The Problem

I cannot find or add the bot to any GroupMe group.

What I've Tried:

Option 1: Search for bot by name in GroupMe

• Opened GroupMe app/web
• Searched for my bot name
• Bot does not appear in search results

Option 2: Using OAuth redirect URL

• Navigated to: https://oauth.groupme.com/oauth/authorize?client_id=[MY_CLIENT_ID]
• Successfully logged in with GroupMe credentials
• After authentication, redirected to https://dev.botframework.com
• Page is blank (see screenshot)

Additional Info:

• Bot works perfectly in Azure Web Chat
• All channels show "Healthy" status
• No errors in Azure logs
• GroupMe application is created and configured at dev.groupme.com

Questions

1. What am I missing to actually add this bot to a GroupMe group?
2. Is there a separate step to create a GroupMe bot instance (beyond the OAuth application)?
3. Should I be using dev.groupme.com/bots/new to create something additional?

Environment

• Azure AI Bot Service (Web App Bot)
• Bot language: Python
• GroupMe account: Active and working

Any help would be greatly appreciated!
