Hello,
I didn't know that there was a package for microsoft one drive, that's cool. We have one drive at work and it is tied to our network. You can map the drive and then reference it with which ever letter you choose, a.k.a, L:\folder\file. xlsx.
I personally just copy paste the address if I ever need, especially since all my internal GitHub folders are on my one drive.
I've never seen down_load file push a file into a data frame must be a function from that package. You could try readxl if you have the path.
