How to find position of more than one word using Find Text Position activity (or a workaround)



I recently run into issues with the following activity: Find Text Position.
I can make it work with single words, but not with full sentences nor even two words separated by a space.

See example xaml file for the simplest example:
Main.xaml (7.8 KB)

I would like to later use that Find Text Position activity together with Anchor Base activity but the fact that it does not find sentences makes such use unreasonably limited.
