How to claim -Revolut address

Hy there,

I need your support in understanding how can i claim my Night tokens , if at the time of the snapshot my Ada was in a non dApp wallet and i do not have access my private key? Is there a manually way of verifying that i am the owner of the Ada which were mine also when the snapshot was done? Looking forward for your solution or share with me your knowledge on how you claimed if you had also your Ada in a revolut wallet.
