From reading the comments on the thread and some others they use an ESP kit to make custom setups for this, others with more experience with these should be able to help guide you on ideas to help you build out the setup you are looking for.
It’s just called a physical panel board. The other option is to use dedicated remotes that have the option to bind Single, Double, Triple or Hold actions to the buttons they have when not using single buttons for it and building out a custom case around the setup with labels etc.
