Missing Chromecast and other mDNS devices

My HE C-7 (2.5.2.139) is on a home VLAN, and Chromecast devices are on a media VLAN on a Ubiquiti UDM-SE switch where I've enabled mDNS reflector and confirmed my computer on home VLAN is able to discover mDNS devices on the media VLAN. However Hubitat mDNS devices only shows _airplay._tcp.local. that are on media, but no _googlecast._tcp.local. devices.

I've confirmed that I can ping the Chromecast devices on media from home - Is there a way to add device IPs directly that does not rely on mDNS?
