### Describe the bug The property `layoutType` is missing for the `graph.models.Channel`-Object. Without it reading the actual value of a channel is hard. Patching the property can be done with some workarounds using additionalData (see below). The object: <img width="691" height="606" alt="Image" src="https://github.com/user-attachments/assets/aa459053-2cb0-4a74-934a-5a8840bffadb" /> A graph request: https://graph.microsoft.com/v1.0/teams/{team-id}/channels/{channel-id} <img width="324" height="405" alt="Image" src="https://github.com/user-attachments/assets/4e829480-d34f-4a59-af41-6e67fdc88826" /> ### Expected behavior The property should be present in the `graph.models.Channel`-Object. Also an enum for the two allowed values would be nice. ### How to reproduce Simply use some sdk version and try to read or patch the `layoutType` of a channel. ### SDK Version 6.63 ### Latest version known to work for scenario above? none I guess ### Known Workarounds For a patch you can use one of: ``` .getAdditionalData().put("layoutType", "post"); .getAdditionalData().put("layoutType", "chat"); ``` I don't know if there is a workaround for reading. ### Debug output _No response_ ### Configuration This should not impact the issue, since it is not present in the models of the java-SDK. ### Other information _No response_
