Is it possible to customize the request header when fetching swagger files via url ?

Thank you very much for this tool, which has greatly facilitated our development work.
Recently, while using the tool, I encountered a scenario where I needed to define some extra request headers to get the correct file when fetching swagger files via url.
I would like to ask you how this requirement needs to be implemented.Or is it not possible to implement custom request headers in the current version?Thanks.
