Getting List.Count for each column Power Query

Hello,

I have a table like this:

I have been trying to find a way to convert each column so that they are a count of the number of items in each list for each row. One company used to have multiple rows and I used the Group By function first, then Aggregated Rows using List.Distinct so it have me a the result above. The end goal is the count within each list. I have been having the hardest time and am hoping I can avoid having to manually make a custom column for each one since I have like 30 columns. Any help is greatly appriciated.
