RStudio import is just a wrapper around import functions (read.csv, read_csv, read_excel, read_sas and few others, check File > Import Datasets for complete list), it's mostly for a quick interactive work and was suggested because you seemed to have issues figuring out correct file path.
For reproducibility you should just take the code generated by importer and include it to your script or Quarto / RMarkdown notebook. If you plan to render or knit Quarto or RMarkdown documents, it will just not work until you've included all your data import calls there.
