Pilot integration plugins

Hello,

Plug my traefik:2.3rc instance on Pilot works fine, just add :

--experimental.pilot.token="xxxx"

But if i add by example :

--experimental.plugins.blockpath.modulename="github.com/containous/plugin-blockpath"
--experimental.plugins.blockpath.version="v0.1.2"

Traefik return on debug mode :

reverse_proxy_1 | 2020/07/19 08:33:53 traefik.go:75: command traefik error: failed to download plugin github.com/containous/plugin-blockpath: error: 400: {"error":"invalid token"}

Any ideas ?
