Eligible Variable Values for Reference Row Filter

Using the Reference Row Filter and building it into a data app. I need to include a widget to flip the “Include or Exclude rows from the reference table”, the variable for this flag is a string but I can’t figure out what the valid options are for that variable I have tried the following:

• Include

• Exclude

• include

• exclude

• yes

• no

• Yes

• No

• 1

• true

• false

• True

• False

Is this documented somewhere that I missed?
