How to setup 2 or more Netgear AX3000 RAX35 or RAX40 devices in a wireless mesh or bridged mode ?

Looking for a high level step by step tutorial on how to setup Wireless bridge mode on 2 RAX35 or RAX40 devices.  My assumptions are they should be able to form a wireless bridge or Mesh network using the AX channel capabiities.  One will be connected to the WAN (Cable/Fiber/DSL) and in Router mode and the other(s) will be in AP mode over the wireless bridge/mesh.  But not sure where to get started with regards to forming the mesh in terms of the Wifi settings on the AP ???

Is this possible with these devices and if so does anyone have a high level step by step / tutorial on how to setup the additional AP devices ?

Thanks.
