Is there any way to know edge is shown or not?

I am not proficient in ruby, but i put this together using AI and a lot of testing. The script looks at the current selection and updates the toolbar icon state to show soften edges ( all, some, none)

require 'sketchup.rb'

module MP_Extensions
  module MP_Edge_State_Tool
   
    def self.update_icon
      model = Sketchup.active_model
      selection = model.selection
      edges = selection.grep(Sketchup::Edge)

      return if edges.empty?

      # Check the current state of the edges
      all_soft = edges.all? { |edge| edge.soft? }
      none_soft = edges.none? { |edge| edge.soft? }

      if all_soft
        icon = 'all.png'
      elsif none_soft
        icon = 'none.png'
      else
        icon = 'some.png'
      end

      icon_path = File.join(__dir__, icon)
      @cmd.small_icon = @cmd.large_icon = icon_path
    end

    def self.recreate_toolbar
      @toolbar = UI::Toolbar.new("MP Edge State")
      @toolbar.add_item(@cmd)
      @toolbar.show
    end

    def self.toggle_soft_edges
      model = Sketchup.active_model
      selection = model.selection
      edges = selection.grep(Sketchup::Edge)

      return if edges.empty?

      # Check the current state of the edges
      all_soft = edges.all? { |edge| edge.soft? }
      none_soft = edges.none? { |edge| edge.soft? }

      model.start_operation('MP Edge State', true)

      if all_soft
        # Set all edges to none soft
        edges.each { |edge| edge.soft = false }
      elsif none_soft
        # Set all edges to all soft
        edges.each { |edge| edge.soft = true }
      end

      model.commit_operation

      # Update toolbar icon
      self.update_icon
      self.recreate_toolbar
    end

    unless @loaded
      @loaded = true

      @cmd = UI::Command.new("MP Edge State") { toggle_soft_edges }
      @cmd.tooltip = "MP Edge State Tool"
      @cmd.status_bar_text = "Toggle the state of selected edges"
       #update_icon
      
      # Set default icon to "all.png" on load
      @cmd.small_icon = @cmd.large_icon = File.join(__dir__, 'all.png')
      
      recreate_toolbar
    end

    # Add an observer to update the toolbar icon when the selection changes
    class SelectionObserver < Sketchup::SelectionObserver
      def onSelectionBulkChange(selection)
        MP_Edge_State_Tool.update_icon
        MP_Edge_State_Tool.recreate_toolbar
      end
    end

    Sketchup.active_model.selection.add_observer(SelectionObserver.new)
  end # module MP_Edge_State_Tool
end # module MP_Extensions
