How can I find all the columns available in UniProt.ws package for R? I am trying to find the subcellular localization of my 10,000 proteins using UniProt.ws package for R. However, I am unable to find all the columns available for query.

I used another package named Bioconductor which had easy way to lookup all the columns available using COLUMNS(org.Hs.eg.db)

I tried reading the documentation and couldn't find anything which can output subcellular localization. I am new to this field, any help is appreciated.
Do you have a small sample of the proteins you are looking for and what you have tried so far in R using Uniprot.ws ? (including output of it), it could be helpful to identify your problem and how to solve it.

Personally, I would rather consider Bioconductor as a platform for providing R packages dedicated to bioinformatics than a package to analyze data (but it's my opinion, maybe I'm wrong).
