acts_as_state_machine helper method rails 6

i have a verified and unverified states in my booking model, how do i implement helper methods for my views? i would like something like this in my index views.

  <% @bookings.each do |booking| %>
    <%= link_to booking_path(booking) do %>
        <%= booking.name %>
        <% if verified_booking %>/* here is where i want implemented*/
            <div class="pt-4 font-semibold"><i class="fa fa-user-check"></i></div>
        <% end %     
    <% end %>
    </div>
  <% end %>

helper method

  def verified_booking
    !!Booking.verified
  end

booking model

  include AASM
  aasm :column => :state, :whiny_transitions => false do
    state :unverified, initial: true
    state :verified
    event :verify do
      transitions from: [:unverified], to: :verified
    end
  end

ApplicationHelper.rb

def verified_booking(state)
 # check state in the database if it is verified
 # return true if state is verified
 # return false if not verified
end

html.erb

<% @bookings.each do |booking| %>
    <%= link_to booking_path(booking) do %>
        <%= booking.name %>
        <% if verified_booking(booking.state) %>/* here is where i want implemented*/
            <div class="pt-4 font-semibold"><i class="fa fa-user-check"></i></div>
        <% end %     
    <% end %>
    </div>
  <% end %>
