I Want To Recover My Telegram Account

I have been unable to access my Telegram account for about five months because I lost both my phone and the SIM card that was linked to my account, which was registered with a number starting with the country code +234. Since I no longer have this SIM or the device, I cannot receive the login codes and therefore cannot sign in to my account. I am especially worried about my chats, as they include important personal conversations and information that I do not want to lose or risk being accessed by someone else if the phone or SIM falls into the wrong hands. I kindly request your help to regain access to my Telegram account that is linked to the lost number starting with +234. I would like you to guide me on any alternative verification methods you can offer, or any steps I can follow, so that I can securely recover my account and protect my chats.
