R code making 1 column into multiple columns with their unique ID

Currently stuck on a data wrangling question in R. So far I've tried variations of this code using tidyverse package, columns 5 and 6 here were the rating and the user:

df[,5:6] %% 
  pivot_wider(names_from = question, 
              values_from = rating,
              names_sep = .) %% 
  unnest(cols = everything())- df_reformat

Each column will be the question ID and the rows are the scores for each user, ideally clustered by group.

Data structure needed:

Current data structure:

With the rows of each question column contain the rating scores 1-7.

Many of the dimensions are different so it's gets complicated. For example, sales rep 1 has 2 groups (with varying number of users between groups1 and 2) and questions asked (for sales rep 1, group 1, there were 5 unique question IDs but varying number of users). I dropped two questions so the dimensions fit but ideally I'd like to run my CFA with them included.

Thank you anyone that has the willingness to attempt to help!
