Unable to find 'List Contains' function - is it deleted?

Hi Parabola Community.
I am comparing two sets of data and I want to keep the non-matching data. However, I have looked at can’t see any function that does this. It is mentioned there is a List Contains function and there is even a video about it but when I try to search for it - it doesn’t appear?

I noticed it may be now called ‘Find Overlap’ but the option for not contains or advanced settings is in there.

If anyone can help that would be great.


I believe i have found the solution. So within the ‘Find Overlap’ you can select ‘match’ and change it to ‘do not match’ but this option does not appear until you have completed the other initial values.

Hope this helps anyone else trying to do the same thing.
