Help! Tarmac SL7 garmin mount installation

Hi all,
Not really a TR query, but I thought someone on the forum might be able to help.
I’ve just had the new SL7 Pro delivered. It’s a beauty!
However, I am struggling to install the Garmin integrated mount to the Aerofly bars. Can anybody give me any pointers? Thanks in advance.
