Leaking Toilet Pan – O/C’s Insurance?

I've just received a request from a Property Manager to repair a cracked toilet pan within a Rented Unit, and to claim that repair / replacement on the O/C's Insurance.

Whilst I'm confident that the repair / replacement of the toilet pan (a “fixture”) is the Unit Owner's responsibility, PT 4 Div 1 Cl 81(a) of the SCMA defines the “Building” over which the O/C must hold Insurance as including “owners’ improvements and owners’ fixtures forming part of the building other than paint, wallpaper and temporary wall, floor and ceiling coverings” etc etc.

Does this mean that the Unit Owner can request the O/C to claim her costs of effecting the repair / replacement on its Building Insurance, and if so, can the O/C be required to make that claim, or is it discretionary?

Thanks in advance.
