Hi again, how to write following code? I would love to use not(expression) Expected result: ``` not('{US,UK,AR}' && my_table.allowed_countries) ``` raw attempt: ``` sql`not('{ ${array1.join(',')} }') && ref('my_table.allowed_countries') ``` but it produces: ``` not('{'US,UK,AR'}') && my_table.allowed_countries) ```
