Citing R packages with citation managers

I was just working on citing some R packages (including from rOpenSci) in a paper using paperpile citation manager. It doesn’t seem to be easy, at least there’s a recent forum post on that: Citing R-packages with Paperpile - Support - Paperpile Forum

rOpenSci has a great blogpost on the topic: rOpenSci | Make Your R Package Easier to Cite

Does anyone have suggestions to make it easier? Paperpile or zotero? Or helpful points to make to paperpile, which is a paid-for product?
