C#/.Net/AzureFunction/BotFramework development - existing code, new functionality

I have a C# application that I need modified. Here is the application - [login to view URL] I've modified it a little, but I need some additional expert help on extending one of its data repositories to support multiple appId/botId. Right now, when the prep orchestrator and send orchestrators run they work with one bot instance created during startup. I need 1) Extend data repository for notifications to allow for botId/appid/apppassword to be included in the initial message 2) Add those three parameters as inputs into one of the api routes 3) In both prep and send functions, if you look at [login to view URL] it populates appid and apppassword, and then registers a bot or graph service using those credentials. I need to instead use the values from the data repository and on execution. You must be familiar with C#, Azure Functions, .NET development, and Bot Framework. Prior to responding, please review the application on Github above, and understand the requirements. To weed out those who did not read this post or look at the app - with your bid, please answer this question: How does the Azure function "SendFunction" in the app above gets triggered? And what precedes execution of that function? As in where does the data come from? Bids without that answer won't be considered.
