Does Eve Home Switches Need to be Matter?

All my Eve Light Switches (42 of them) are connected to HomeKit. The switches can be “updated” to matter. Do I have to convert them to matter in order to see them in Homey?

Your instructions say this can be done through the Eve App as a bridge without converting to matter. I don’t have any reason to NOT convert to matter. Just a pain to do 42 of them.
