How to access Participant details in teams online meeting ? getting error = Application is not registered in our store

Question

I would like to access the mediaStream property of the participants in online meeting in teams as mentioned in the doc here.
https://learn.microsoft.com/en-us/graph/api/resources/mediastream?view=graph-rest-1.0

1. How to get the call ID?
2. Is there any example available which shows this? ( I am interested in label field )
3. What type of auth flow is required?
4. Deleted permission or application permission?

CLIENT_SCOPES = ["https://graph.microsoft.com/.default"]
@app.get("/api/auth/login")
def login():
    auth_url = msal_client.get_authorization_request_url(CLIENT_SCOPES)
    return RedirectResponse(auth_url)
@app.get("/api/auth/callback")
async def auth_callback(request: Request):
    try:

        code = request.query_params.get("code")
        credential = AuthorizationCodeCredential(
            tenant_id=TENANT_ID,
            client_id=CLIENT_ID,
            client_secret=CLIENT_SECRET,
            authorization_code=code,
            redirect_uri=REDIRECT_URI
        )
        graph_client = GraphServiceClient(credentials=credential, scopes=CLIENT_SCOPES)
        calls = await graph_client.communications.calls.get()
        for call in calls:
            print(f"Call ID: {call.id}")

error: MainError(additional_data={}, code='UnknownError', details=None, inner_error=InnerError(additional_data={}, client_request_id='05143fb2-76f6-4707-9342-84739c95101a', date=DateTime(2024, 7, 16, 15, 44, 28, tzinfo=Timezone('UTC')), odata_type=None, request_id='1ef5bac6-6262-4267-86e2-8f2ecbcbfaa5'), message='{"errorCode":"7503","message":"Application is not registered in our store.","instanceAnnotations":[]}', target=None)

Hi @Hashaam Hasaan

Listing all calls by calling the GET /communications/calls endpoint is not supported. This API endpoint also does not exist in the Graph API documentation. Only the GET /communications/calls/{id} endpoint is currently supported.

To get the call id, you can find it after creating the call.

Note that the GET /communications/calls/{id} endpoint only supports application permissions, you need to create an application-only context using the client credentials flow.

scopes = ['https://graph.microsoft.com/.default']
# Values from app registration
tenant_id = 'YOUR_TENANT_ID'
client_id = 'YOUR_CLIENT_ID'
client_secret = 'YOUR_CLIENT_SECRET'

# azure.identity.aio
credential = ClientSecretCredential(
    tenant_id=tenant_id,
    client_id=client_id,
    client_secret=client_secret)

graph_client = GraphServiceClient(credential, scopes) 

result = await graph_client.communications.calls.by_call_id('call-id').get()

Hope this helps.
