Aws_api_gateway_resource and path_part wildcards

Hi, I have a very basic resource that looks like this (for a lambda integration)

resource "aws_api_gateway_resource" "proxy" {
  rest_api_id = aws_api_gateway_rest_api.example.id
  parent_id   = aws_api_gateway_rest_api.example.root_resource_id
  path_part = "users"
}

My assumption was that this was going to allow me to hit urls like : https://xxxxxxx.execute-api.us-east-1.amazonaws.com/test/users/1234/

However, it only lets me hit https://xxxxxxx.execute-api.us-east-1.amazonaws.com/test/users/

Most examples and tutorials. love to show off “{proxy+}” but not much else.

I’m don’t really know what I don’t know. Can someone point me at what words I should be googlin please?

Thanks
