Description of the issue

I have a Matter product that has passed the CSA certification, the device can join to the network by scanning the QR code or 11-or-21 digit pairing code, but when being discovered did not display any identifying information. This resulted in our ITF test failing, so does Android Google Home app not support discovering the identifying information for matter device? Please contact J.Li6@ledvance.com

Reproduction Information

1. Make sure your matter device is in a reset state
2. Open Android Google Home App
3. click "Devices" -> "Add" -> "Google Nest or partner device" ->choose the home-> Next
4. After scanning, it will list the nearby devices Result : The UI only lists "Matter-enable device", not my device identifying name. I have registered it to the CSA DCL

App Info

Google Home App Version: 3.26.13
Platform Version/OS Version: Android 14

Device Info

Thread Version On Device (if applicable): Matter over wifi
Firmware Version: 1.0

Dear developer,

Thank you for reaching out to us. Please try the following steps for troubleshoot -

As indicated in the documentation , when adding / removing a device, ensure to do this from your third-party app (not from the Google Home app (GHA)). Do not remove the device if there is only one device in your app that is account-linked, as this will cause a sync error.
Ensure that Report State has been implemented correctly. Report State is an important feature which lets the Google Home Action proactively report the latest status of the user's device back to Google Home Graph rather than waiting for a QUERY intent.

You can inspect if the device status is correctly synced on HomeGraph Viewer, and check if the status matches what is shown on the Google Home App.

If the issue persists after troubleshooting, to help us reproduce it, please share the following information with us:

Sync Response(JSON format)
Relevant GCP logs.
Project ID.

If you have any further questions, please feel free to reach out to us. Thank you.
