Cannot Reset Security Questions

My name is Star and I am trying to use 'find my iphone service' to locate my father: Haviv, who has dementia.

When I login to his account: ***@gmail.com, after I specify the correct password, I am requested to answer some security questions that I do not have the answer for.

Can you please enable me reset these questions so that I can use the service and find my father when needed?

My father's backup email is mine: ***@gmail.com.

I can provide more details in case needed.

Thanks in advance,

Star
