Verizon Fios - Google Mesh Network

[MarkJS1]

I have Verizon Fios fiber at my house and have been using the Verizon router for about 5 years now. I have quite a few devices on my network with static IP addresses. I wanted to obtain some more coverage in my backyard and recently purchased a Google Mesh setup with a few access points. 

Everything is set up and both networks work fine. The only issue I have is that Verizon operates on one subnet (192.168.2.xxx) and the Google mesh operates on another (192.168.86.xxx) and I can't get devices connected to the two separate networks to talk to each other (chromecast, network printer). 

I really don't want to disable the Verizon network and then have to set up everything on the Google one. I'm also not a network guru, and don't quite understand routing and the other technical pieces. Does anyone have some basic instructions on what I rules need to set up in my Verizon router so that traffic from the two separate subnets can communicate with each other?

Thanks in advance

Check if the Google mesh can be configured for "access point" mode.  That will prevent it from creating it's own network.

Verizon router supports static routes, but Google Mesh likely does not support disabling the Network Address Translation, you can only put the Google Mesh into the so-called "Bridge Mode."
