For page properties how to write expressions - Syntax

Summary:

In our organization we have written EL Expression to control the page properties like add, edit, Complete, Cancel, Delete and Evaluate Task as a Worker/Manager.

In Redwood how is this achievable we have tried to use the below expression based on the Guided Journey documentation but this is not working.

[[ $application.user.roles.includes('FJ_HR_SPECIALIST_BY_AOR_INCL_HIDDEN_DATA') ? 'false' : 'true' ]]

Can someone let me know if the syntax is correct and how to make this work.
