Simulink "Initial state" vs. Simscape "Operating Point"

Hi,

I have a Simulink model that has Simulink blocks as well as Simscape/Simscape Electrical blocks.

I want to simulate this model up to certain operating point, save this state to, then, initiate other simulations starting from this previously saved operating point.

Within "Configuration Parameters > Data Import/Export" there is field "Initial state" in which I can use a file of OperatingPoint type:

But, within "Configuration Parameters > Simscape" there is also a field named "Operating Point" in which I can use a file of OperatingPoint type:

My question is: Do I have to use these both initialization fields?

I saw in some MathWorks documentation, such as "https://www.mathworks.com/help/slcontrol/ug/frequency-response-estimation-for-power-electronics-model-using-prbs.html", only the "Initial state" field been used. But, as I didn't understand the difference between both fields, I do not know how to properly use them.

Thanks.
