Description

I would like to generate a client which is required to use a basic authentication to connect to the service. Unfortunately I do get an error

value withCredentials is not a member of sttp.client.SpecifyAuthScheme[sttp.client.Identity,Either[String,String],Nothing]

Checking sttp client source code I can see that real function name should be basic. https://github.com/softwaremill/sttp/blob/61dc6aecc93c70891ba7c74bc100ed5e65a94777/core/src/main/scala/sttp/client3/RequestT.scala#L396
