TLS 1.3 config for Traefik v1

Traefik Traefik v1
1

Hi! I've searched through the forums and it look like TLS 1.3 is available in the latest builds, 1.7.18 and 2.0.2.
I use traefik as a very basic reverse proxy, but I failed to configure TLS 1.3 and don't see the correct examples for my case. The config looks like this:

defaultEntryPoints = ["http", "https"]

[web]
address = ":8080"
  [web.auth.basic]
  users = ["admin:%^#$@^$#%&$^%*^%*&#%@$%$%$&^*&^"]

[entryPoints]
  [entryPoints.http]
  address = ":80"
    [entryPoints.http.redirect]
      entryPoint = "https"

  [entryPoints.https]
  address = ":443"
   [entryPoints.https.tls]
    minVersion = "VersionTLS12"

[file]

[backends]
  [backends.backend1]
   [backends.backend1.servers.host]
    url= "http://192.168.0.22:80"

 
[frontends]
 [frontends.frontend1]
  backend = "backend1"
  passHostHeader = true
  permanent = true
 [frontends.frontend1.routes.host]
   rule = "Host:host.domain.com"

[acme]
email = "admin@mail.com"
entryPoint = "https"
onHostRule = true
[acme.httpChallenge]
  entryPoint = "http"

Simple change to minVersion = "VersionTLS13" doesn't seem to work. So, what it the supposed working config for v.1.3?
