Telegram Account Compromised and Recovery Email Needs to Be Removed

I use Telegram on my iPhone and until last week I was able to access my account without any issues. When I recently tried to log in again, I saw that an email address that does not belong to me is shown on the screen. Telegram now asks me to enter a code that is supposedly sent to that email address, but since this email is not mine, I cannot receive the code and I am completely locked out of my own account. I am very worried that someone else may have added their email to my account or that my account has been compromised. I request that this wrong email address be removed from my account and that my access to my Telegram account be restored as soon as possible.
