Issues with viewing footage shoot using HLG2 picture profile

Hello everyone, I recently bought a Sony A7 III camera and decided to use a HLG2 picture profile. When I view my footage on computer it's nice and as it's expected to be but as soon as I upload it to FCPX it automatically changes all the colours and basically overexposes whites. When I try to change the input LUT of the camera from Inspector-- Info-- General , it shows only some basic options with SLogs. Anyone having suggestions of what in my setup went wrong and what should I do to change it?
