You've missed the movement of the Collector#filter being in the options.

Just a heads up that message commands are going to be obsolete.

That means moving forward you will need to update this to use an interaction instead of a message.

You may also want to use buttons for navigation instead. You can also use select menus for category based filtering and navigation (as below, my update does this - reactions, buttons, menus) to take use of all v13 features.
