exact logistic regression - elrm package

I tried to perform an accurate logisitc regression on R, and google advises one way: the elrm package (for exapmle: https://rdrr.io/cran/elrm/man/elrm.html, https://stats.idre.ucla.edu/r/dae/exact-logistic-regression/)
But now it is not available in CRANE also I cant isntall from archive.
Either way, it is also not available package ‘elrm’ is not available (for R version 3.4.3)
Are there any alternatives to this?
Thank you.

You can install an archive version using

devtools::install_version("elrm", "1.2.2")
