i did eventually find the answer at the bottom of the OneMesh page. Hopefully anyone searching for the same answer will find this post.

Q2: How to set up a mesh network when there are more than two repeaters joining into the network?

A2: Generally we suggest connecting all the repeaters to the router for better performance. Customers can also connect one repeater to another repeater which already gets connected to the router, however we don’t recommend you to add more than two repeaters to one single link chain in consideration of the Wi-Fi quality.
