odata.context doesn't include group prefix

[MFernando-MSFT]

I'm configuring OData inside of a group prefix
configure.MapGroup("/mygroup").MapODataRoute("routename", "routeprefix", ...)

With that I can call the API on
https://example.com/mygroup/routeprefix/etcs('...')

but the result I get has the field @odata.context with:
https://example.com/routeprefix/#metadata#etcs/$entity

instead of
https://example.com/mygroup/routeprefix/#metadata#etcs/$entity

In other words, the prefix I created with MapGroup (/mygroup) isn't present on the odata.context response.

I'm using OData 7.7.7

Seems like MapGroup found in EndpointRouteBuilderExtensions injects a RouteGroupBuider .
However the code below has a feature gap since the code was meant to work with a much Older version of Net core.

WebApi/src/Microsoft.AspNetCore.OData/Extensions/Endpoint/ODataEndpointBuilderExtensions.cs

Lines 572 to 577 in 59f387a

	Action<IContainerBuilder> builderAction = ConfigureDefaultServices(builder, configureAction);
	IServiceProvider subServiceProvider = perRouteContainer.CreateODataRootContainer(routeName, builderAction);
	// Resolve the path handler and set URI resolver to it.
	IODataPathHandler pathHandler = subServiceProvider.GetRequiredService<IODataPathHandler>();
