Visiting the Louvre as a disabled person

Hi, I am an intellectually disabled person from Australia visiting Paris. I know that I can enter the Louvre for free as a disabled person but I am not sure about providing proof. I don’t have a simple card to prove that I am disabled as we don’t have something like that in Australia but I have digital documentation of my disabilities. How can I prove my disability? Will I be able to show them my documentation and that will suffice?

Thank you!
