Extracting partial string from cells in power query

Hi,

I am trying to extract a partial string of text from a notes column and place that partial string of text into a new column. I am using power query, and I feel like there must be a way to to do this, but I can't quite figure it out. Any ideas?

The attached example spreadsheet has the "original" table on the left, and the "desired outcome" table on the right. (not thru power query, I added that 3rd column manually)

EDIT: As I think about it, being able to filter based on a partial string in power pivot would also work. Whatever is easier.
