MAX HD Dome Pro - using WiFi as an accesspoint

I recently installed a MAX HD Dome Pro 5G on my sailboat mast spreader. I have an AP One AX access point in the sailboat cabin. I was thinking about configuring the WiFi radio in the dome for WiFi as WAN but don’t think this will be that useful given the 5G capabilities. But now I’m thinking of using it as a second access point and try to broadcast wifi to the beach. I would disable the WiFi as WAN and only use it as an AP. I’d prefer to have it mesh with the AP One AX but I’m ok using a different SSID. Has anyone done this? Is this a good application of the wifi? Any advice on how to set it up?
