Teams not sending "composeExtension/anonymousQueryLink"

[gregghz]

My manifest.json includes:

"messageHandlers": [
  {
    "type": "link",
    "value": {
      "supportsAnonymizedPayloads": true,
      "domains": [
        "my.domain.org"
      ]
    }
  }
]

I've uploaded the app so that it shows up in "Built for your org" as instructed here: https://learn.microsoft.com/en-us/microsoftteams/platform/messaging-extensions/how-to/link-unfurling?tabs=desktop%2Cdotnet%2Cadvantages#enable-zero-install-link-unfurling

I have implemented the endpoint to handle those requests (I can manually hit it via curl). When I paste a link from the correct domain, in the UI nothing seems to happen. The link is there but never unfurls. If i watch the network tab, I can see that MS Teams is attempting to use the schema.org unfurling described here: https://learn.microsoft.com/en-us/microsoftteams/platform/messaging-extensions/how-to/micro-capabilities-for-website-links?tabs=article -- it makes a request to /info?url=... (which does a GET directly to the url pasted) instead of the /invoke that I see for unfurls while the app is installed which does the POST to the registered endpoint handler.

What am I missing for registering my app to handle zero-install unfurling and be able to test it in my teams instance?

We also see that the link is not unfurling. We raised a bug for the same. We will keep you posted on the updates. Thank you.
