How to build a dynamic minimal api with RequestDelegateFactory, and the api description can be shown in swagger ui

[AshWang-whm]

I'm facing a challenge that how can I create a dynamic api with [RouteHandlerBuilder.MapMethods] by RequestDelegate, and the api parameter and return type can be shown in swagger or how can I add customer metadata into [IApiDescriptionProvider] ?

Here is the code
WebApplication1.zip

there's two way to add dynamic api ,one is build a Delegate by object and bind the MethodInfo , the swagger ui can display the Api Group and all the description , but the defect is it instance object look like use AddSingleton , All dependencies use the singleton pattern

create the Delegate with instace!

the other way is use RequestDelegateFactory , every thing is ok but the swagger can't display the api description, I don't konw how to add the metadata into the [IApiDescriptionProvider].
