String array in query parameters swagger

Question

I'm working on a project where there is an endpoint that receives a list of strings in the parameter, as shown in the code below:

public class PaymentFilter
{
    public List<string> Status  {get; set; }
}

[HttpGet]
public IActionResult Get([FromQuery] PaymentFilter filter)
{
    ...
}

However, in the swagger interface the status list is not reflected, as shown in the image:

How do I enable entries for the status list?

Not sure if this is what you're asking but to enter values for the array in swagger click "Try it out" then "Add string item" — haldo

I am using dotnet core 3.1 with Swashbuckle and when I use the same type ([FromQuery] List<string> ids) of param, I don't see it returning as a list of strings but as the comma-separated single string value. Any idea? Btw, tested this out with v6.1 and it works just fine. Not sure if its a bug with package..
