Can't get bearer token from request in C# function

[myers-gh1328]

In the JS example for custom role assignment at https://github.com/staticwebdev/roles-function/blob/main/api/GetRoles/index.js the bearer token for calling graph is retrieved by setting a const user = req.body and then getting the token from user.accessToken

The request body in C# is a stream that does not contain anything. What is the C# equivalent to the js example code?

The format of accessing fields in the request body is the same for this context as for normal HTTP trigger C# functions (https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-http-webhook-trigger?tabs=csharp).

The following code snippet can be used to access the access token for example:

string requestBody = string.Empty;
using (StreamReader streamReader =  new  StreamReader(req.Body))
{
     requestBody = await streamReader.ReadToEndAsync();
}
		
dynamic data = JsonConvert.DeserializeObject(requestBody);
string accessToken = data?.accessToken;
