'Update all existing records with computed value of another field in Rails

class UpdateBrowserLanguageInInsightsVisits < ActiveRecord::Migration[6.1]
  def change
    Insights::Visit.update_all("browser_language = Iso639[context[`browser`][`language`]]&.name")
  end
end

I want to update all existing records with computed value of another json field called "context"

How do I get reference to another field in table inside update_all?
