APX 320 X working with UTM SG or not ?

Hello,

My IT service puchase some SOPHOS APX 320 X.

I have Sophos UTM SG 410 with 9.713-19 firmware version.

I have read that those AP will only work witch Sophos Central (in french on the capture)

But when I opened the AP Box, I found a flyer that says if I have an SG Series, I must have 9.711 firmware or later.

The wireless live log says that the AP model is not recognized ...

Right now, I don't know what I should believe and what should I do. 

All my APS are managed with the SG embedded controller.
