Trouble installing package ‘export’ after upgrading R version. Is there an alternative to this package?

I keep seeing this error: package ‘export’ is not available (for R version 3.6.3).

I tried various ways, such as:

install.packages("export")

devtools::install_github("tomwenseleers/export")

I successfully used this package in the past and would very much like to use it again!
