I am creating shiny applications using the learnr package. I am trying to pass the user_id through custom headers as explained in https://rstudio.github.io/learnr/publishing.html#Tutorial_Identifiers
My question is will these custom headers(supported by learnr) be available(whitelisted) in Shiny open source server. Or these headers will also be available only in Shiny Server Pro?
Thank you in advance.
