How can I use context.log in Azure functions?

I don't know how to use context.log with serverless-express and Azure functions. Please tell me how to use context.log.

No file, test, or entry point is named. Start by checking whether Azure Functions and context.log are supported by this AWS-focused serverless-express repository, then review the existing issue discussion. Done would be a documented, repository-supported answer or a clear explanation that the requested integration is outside the project’s scope.
