R Googlsheets: Unable to use `gs_auth()` in googlesheets package - Sign In With Google Temporarily Disabled App Not Verified Issue

googlesheets4 will replace googlesheets package very soon (by March 2020). Most of the functions performed by googlesheets can be handled by googlesheets4 currently, except for writing to specific cells.

googlesheets4 has a oauth authentication using Gargle (similar to googledrive package). More info can be found here - https://github.com/tidyverse/googlesheets4
