Can I refuse an insurance company’s video interview?

A few months ago, I was helping a family friend who had broken their leg. I was driving them to and from their doctor/physio appointments because they couldn’t drive themselves. The car is theirs, and I was simply the driver who was listed on their insurance.
One night around midnight, someone crashed into the front of their car while it was parked. The other driver was there, and my friend exchanged details with them. The other driver was clearly at fault.
We had a physio appointment the next morning, and I was staying with my friend at the time, so I was the one helping them get around.
My friend then lodged an insurance claim. However, the insurer apparently became suspicious that my friend was impersonating me when making the claim. They asked to speak to me, so I got on the phone with them and answered their questions.
Some of the questions felt very strange and suspicious to me, such as whether I was actually in the car, who witnessed the accident, who called the police, etc. Now they’ve contacted me saying they want to do a video interview with me.
I’m honestly pretty uncomfortable with the whole situation. I wasn’t the person making the claim, I’m not the policy beneficiary, and I was only helping my friend with transportation because they couldn’t drive.
Can I simply tell the insurance company that I don’t want to participate in the video interview and that I want to withdraw myself from the claim? Or am I legally/contractually required to cooperate because I was the listed driver?
I’m in Australia, if that makes a difference.
