Dynamically keep last entry in table & expand section

Hello, I am connecting to a folder with several files. There is a new file added each week to this folder. I'd like to only source data from the most recent file updated. I'll only need to expand the "Transform File" column for this most recent entry. I added an index column and was thinking before I expand the "Transform File" column, I will dynamically keep only the max Index. Can someone please advise how to do this?

#"Last Row" = Table.SelectRows(<previous query step here>, each [Index] = List.Max(<previous query step>[Index]))
in
#"Last Row"
