How to serve pre-compressed files with Caddy v2

I would like to know how to serve pre-compressed files with Caddy v2. Example: when the browser requests the resource /js/app.js and header accept-encoding: gzip, if the resource exists with an extension gz, like /js/app.js.gz, so the response should use the compressed file with the appropriate response header set (content-encoding: gzip).
