Today, many R packages are pre-installed on the standard clusters on Databricks. Libraries like "tidyverse", "ggplot2", etc are there. Also the great library "readxl" to load Excel files. But unfortunately, its counterpart "writexl" is not pre-installed. This means I need to install it whenever I run a notebook, as I don't want to install library on my cluster, as only a few notebooks use this library. How can I request libraries like "writexl" to be installed by default? Then please also install "igraph", "htmlwidgets", "htmltools", ... .
