OpenAPIRouter not included in lagom-openapi-scala-api

[ASchmidt84]

Hi,
I updated to version 1.3.1 and had to see in my API a deprecation warning. Their is showing I should use OpenAPIRouter.
Nothing simpler than that. I was wrong :(
The lagom-openapi-scala-api does not include them. In readme the "lagom-openapi-scala-api" should use in api sbt specification.

Should I now only use the "lagom-openapi-scala-impl"?

Thank you.

val lagomOpenapiVersion = "1.3.1"
val lagomOpenapiApi = "org.taymyr.lagom" %% "lagom-openapi-scala-api" % lagomOpenapiVersion
val lagomOpenapiImpl = "org.taymyr.lagom" %% "lagom-openapi-scala-impl" % lagomOpenapiVersion
