R-CMD Check Warning - Missing link or links in documentation object

[jan-abel-inwt]

I want to get rid of the following warning in the r-cmd check:

* checking Rd cross-references ... WARNING
Missing link or links in documentation object 'fullJoinByExistingKey.Rd':
  ‘[dplyr:join_by]{join_by()}’ ‘[dplyr:join_by]{?join_by}’
  ‘[dplyr:cross_join]{cross_join()}’

My roxygen comment of this function looks like that:

#' Full Join By Existing Key
#' 
#' Filter for existing keys in y. Join y only on existing keys.
#' 
#' @param nameOfY name of y, used only in warnings
#' @inheritParams dplyr::full_join
fullJoinByExistingKey <- function(x, y, by = NULL, nameOfY = "") {

The relevant line from the Rd File generated by roxygen2 :

\item{by}{A join specification created with \code{\link[dplyr:join_by]{join_by()}}, or a character
vector of variables to join by.

...

To join on different variables between \code{x} and \code{y}, use a \code{\link[dplyr:join_by]{join_by()}}
specification. For example, \code{join_by(a == b)} will match \code{x$a} to \code{y$b}.

...

To join by multiple variables, use a \code{\link[dplyr:join_by]{join_by()}} specification with
multiple expressions. For example, \code{join_by(a == b, c == d)} will match
\code{x$a} to \code{y$b} and \code{x$c} to \code{y$d}. If the column names are the same between
\code{x} and \code{y}, you can shorten this by listing only the variable names, like
\code{join_by(a, c)}.

\code{\link[dplyr:join_by]{join_by()}} can also be used to perform inequality, rolling, and overlap
joins. See the documentation at \link[dplyr:join_by]{?join_by} for details on
these types of joins.

...

To perform a cross-join, generating all combinations of \code{x} and \code{y}, see
\code{\link[dplyr:cross_join]{cross_join()}}.}

What did I do wrong or is this a bug?
