How to write EL Expression to hide a button based on user's country

Content

Hi All,

We have a requirement to hide a button only for US employees, for rest it should be visible.

I am planning to write an EL expression for the same but dont get any reference to pull employee's LE, LDG or Business Unit to determine employee's country.

May I know the way to determine employees country?

Also, may I know the EL syntax for "LIKE". For example how do wire user.name LIKE 'abc' in EL Expression.
