Combining AP's on one SSID, and removing default SSID's from AP units

Hello,

I have a Max BR2 router and 2x AP One Ruggeds on a network. I do not want to use InControl2 software so I am trying to configure 1 SSID and have the MAX BR2 and the 2 APs to show on a single SSID through the Web Admin page.
I cannot find where to add the SSID onto the AP rugged and remove their default SSID.
I just need to be pointed in the right direction on a setup manual or something similar if possible?

Thanks
Nick
