[Help] Documentation about EndponintManager

[Yuan-Quan]

Sorry for asking for help with issues.

I'm currently working on a project, in which users upload files, and then serve the processed information of the file on an endpoint.

I've read this guide and this example in it:

@code {

    [Inject]
    IApiProvider ApiProvider { get; set; }

    [Inject]
    IEndpointManager EndpointManager { get; set; }

    ApiDefinition SelectedApi { get; set; }
    string EndpointRoute { get; set; }

    private void Create()
    {
        var endpoint = new EndpointDefinition(EndpointRoute, SelectedApi);
        
        EndpointManager.CreateAndAdd(endpoint);
        
        EndpointManager.Update();
    }

}

I'm very new to ASP.Net dev, I'm not familiar with Razor and Blazor.

I think I've reviewed all the documentation and examples and didn't see more about this EndpointManager.
How could I access/inject this IEndpointManager instance to create an endpoint in my code?
