FF Account Recovery Problem

I am writing because I lost access to my Free Fire account after my phone broke and I would like to ask for restoration of the account. I used this account on my old phone and now, on my new device, I cannot log back in and I no longer remember which login method I originally used. The account I want to restore is on the Czech region/server and the UID is 7850489225. I last used this account approximately in 2022 on my broken phone. Since I do not remember the original login method, I am unable to connect the new device to this existing account and the game only offers me a new start instead of my old progress. I kindly ask you to help me restore access to this Free Fire account linked to UID 7850489225 on the Czech server, or to guide me step by step on how I can recover it, as I could not find a way to contact support directly from the game. I am ready to provide any additional information or proof you may need to verify that I am the owner of this account. Thank you in advance for your help and I look forward to your response.
