[vinlamba09]

Is your feature request related to a problem? Please describe.
I want to develop a bot that also runs in M365 Application. Right now I can config the Azure Bot Service via Portal to include M365Extensions channel as well, but it's not possible to do this via Bicep.

Describe the solution you'd like
Earlier the similar work was done for Outlook channel via this request : #5085
Can we have the similar work done for M365Extensions channel. This channel is now available in new swagger file of Azure Bot Service : https://github.com/Azure/azure-rest-api-specs/blob/main/specification/botservice/resource-manager/Microsoft.BotService/preview/2022-06-15-preview/botservice.json#L2822

Confirmed that Bicep does not have M365Extensions channel available.

Considering that it is available in the REST API spec swagger, it may be that we're not generating the types correctly. @jeskew and @anthony-c-martin do you think you can check whether our types generation is working correctly?

[anthony-c-martin]

The changes have only just been merged into the public specs repo (Azure/azure-rest-api-specs#22077), so I expect this'll be picked up by the next release of Bicep once type generation runs again - I have no reason to suspect a problem with our type generation.

The M365Extensions channel was added to the generated types in https://github.com/Azure/bicep-types-az/pull/1289/files#diff-28f85781c161b601aff6996ebff7a3f5857e288aa4ebec3e205b6c3edaa7f649R26 and will be included in the next release.
