ASP.Net Open Api specify endpoint section

Question

I generate an endpoints via minimal api and also try to generate a documentation with Microsoft.AspNetCore.OpenApi package, but I don't know how to set a section and all my endpoints appears in single section in Swagger.

By sections I mean something like that (on screenshot there are sections visible in Swagger when an endpoints are generated with controller, each section name is a controller name)

How can I specify a section for an endpoint?

Thanks for this question I found out the way to do it.

routeHandlerBuilder.WithOpenApi(x =>
{
    var tag = new OpenApiTag()
    {
        Name = "<your section name>"
    };
    x.Tags = [tag]; // in C# < 12 new List<OpenApiTag>() { tag }
}
