Eero wifi devices and zigbee support

I bought a set of 3 eero 6e pro Wifi APs to demote my AVM Fritzbox to modem only. The Wifi of my 7490 seemed to cause many problems and the slow interface was awful. So far I am happy with the eeros but my additional intention was to make my zigbee mesh bigger as they are advertised being zigbee repeaters only. But to make my existing (homey-) zigbee mehs bigger I need to introduce the eeros to home somehow. Maybe as generic zigbee device. But this doesn’t seem to be possible. Is it a viable workaround to create a new eero based zigbee network and to add all the devices there and then use the Alexa Homey App to make of the devices in Homey?
