Why QSimOptions is throwing error when use_sampler disable_gpu are used ?

[ShashiQubit]

`TypeError Traceback (most recent call last)
Cell In [9], line 2
1 ngpus = 1
----> 2 qsim_options = qsimcirq.QSimOptions(
3 max_fused_gate_size = 2
4 , cpu_threads = 1
5 , gpu_mode = ngpus
6 , use_sampler = True
7 , disable_gpu = False
8 )
9 qsim_simulator = qsimcirq.QSimSimulator(qsim_options)

TypeError: init() got an unexpected keyword argument 'use_sampler'`

It's working fine when these 2 options are removed. I am using windows wsl to run it locally using conda installation.
The documentation clearly has these options. Link to QSimOptions

Because the documentation is specific to our cuQuantum Appliance docker container. The cited option is not available in the public qsimcirq.
