Is there a way to review beneficiary changes on a group policy?

My father passed away two weeks ago and on his deathbed he made it known to my brother and I that we were the beneficiaries of a group life insurance policy through work and asked that we share some money with his girlfriend. While going through his paperwork last week I noticed that his ex wife was the beneficiary prior to 2023 and last year he received a confirmation via mail that his beneficiaries changed but I couldn’t see how. That was the last document I could find regarding the policy. This week when my brother called the life insurance company they told him that my father’s ex wife was the only beneficiary listed on the policy. My brother and I were always on the policy as contingents so it doesn’t make any sense that we would have been removed completely. My concern is that my father’s ex-wife has been convicted of fraud and forgery before and changed the policy to benefit herself. She could have had access to his work benefits portal. She has also been calling around about other benefits and presenting herself as his current wife. Is there a way that I can request to see when and how the beneficiaries were changed? How can I look into this before the insurance company pays out?
